I would like to go on a different approach. First, I want to trash the social stereotypes (man should be older/wealthier than woman), assume perfect parity between men and women, and remark the OP has not made additional statements on the boss's relational status (if she is engaged already or not) or his compatibility with the boss. Let's go split from the personal and professional point of views
You have a crush for a person. That is perfectly natural because we are humans. I wouldn't suggest you to refrain from going further on grounds that she has more power than you (stereotype), or older (stereotype). I don't know the real situation, but if you could get to know more from the other person, you could also discover whether she may match you. This part of the answer isolates the OP and the boss from the workplace context. It's like someone on Interpersonal SE asked the same question about a woman sitting at a social event.
If she doesn't match you, you should go on on your own interest and find someone else. If she might ever match you, that could become the chance of your entire life. You should not use the social stereotypes and the professional barriers to stop you from growing a working relationship.
At the same time, you must act correctly. If you choose the path to show your feelings to the directly interested party and get a refuse, be prepared to accept a definitive no and face the consequences of which I will talk later. I am not encouraging stalking or similar, I just want to say that if you feel it is worth your romantic life, you can choose to bet on that.
On the contrary, acting like you are doing indeed harms your and your social life. If you don't come to a conclusion soon you will be staring to this person for your entire life, showing weakness and awkwardness. Even if this was not professional context, being in crush of a single individual is bad and can lead, in my opinion, to mental
disease problems, mainly becoming incapable of a normal social life like the others. You said yourself that staring at her has consequences over your work.
Life happens. Couple breaks and change. Betrayals, while immoral for some, happen often. Older women are happy with younger and shorter men. Models (while often) do not always marry actors of footballers. Men and women find toy-boys/girls. We are not necessarily talking about full-life commitment here. I am personally talking about mutual consent. Everything consensual is fine to me, regardless of personal stories.
That is your choice. If that is yes, congrats! If that is no, respect her and her decision. Do. Not. Stalk. Her.
And I am not necessarily endorsing you on going forward. Try to know the person more to see if you match her
Conclusion: it is the OP's choice to decide whether to go on or give up. I want to respect his personal commitment into the boss.
It is well debated that having any kind of friendship or relationship with a boss can cause harm because of conflict of interest. As others have noted, it is not uncommon to have relationship between peers or people with different responsibilities but working in different parts of the company.
That said, you are likely to show attraction (i.e. your coworkers will guess right) by your behaviour. It must come to a stop as soon as possible.
Consequences are IMO hard in terms of social life at work: if word happens to spread that you have attraction for someone at office and were refused, you may be pointed to be that one for the rest of your entire work career. Everyone will think about you as "the one who was in crush for the boss". This, depending on your workplace, may have silly bullying consequences. Being "that guy" forever is also a soft-bullying in my opinion.
If you get angry easily at defending your boss you will likely lose credibility in other subjects.
And of course the worst that can happen goes between HR and a charge for harassment.
Professionally speaking, despite your choice to really try to get more friendly/intimate with your boss, you must act immediately. I suggest three steps:
- Immediately: do your best to control yourself
You know that you are staring, you know you are getting angry easily. Then, avoid the line of sight if you can, try to not join conversations about your boss; walk away from break room if necessary.
This step is not sufficient, because you will be feeling under pressure of controlling yourself. This has a negative effect on your state of mind.
- After that: try to get more distance
This works against you. You just began your first job, so going to HR and asking to be moved to another team/office for personal problems with your boss couldn't go easily if you want to hide your attraction status. And speaking about that to HR is a bad idea. Seniority counts here.
The best option is to consider a different occupation in your case. Bonus point: if you ever happen to stay in contact with your current boss after you quit, growing a real relationship is the greatest thing that can happen!!!! But as I said before, I make no assumptions on your real chances. Do not count on that!!
Yet again, do not steal/stalk her number. If you plan to go, try to ask directly to stay in further contact. All future choices of communication depend on your wise.
- On the long term: seek help
Friends, family, professional consulting are all great ideas. I have read questions about start dating someone else. Yes, that will help a lot release the tension, as you will be probably thinking less to your current boss and more to one or more individuals. Often dating is seen as a distraction.
I would go for the professional consulting in this case. We all have feelings as humans, and in fact in the first part of my answer I did not want to suggest stop following your feelings.
Surak teaches us that we should not necessarily bury our feeling, but learn how to leave with them, to control them and not have them to control us.
You should ask for help to get a training on improving your emotion control. I also think that your fragility in handling emotions could easily bar you from finding a different partner.
