I'm in love with my male coworker
Can't you just be friends and not more?
I don't think I can do that
I hear you, but having a romantic relationship in the workplace can be very risky and can jeopardize your professional career. You should try to look for a mate outside of work so there are no conflicts while on the job. Otherwise you both might end up being hurt and get fired.
I don't care and I'm going to continue with this romance. I'm going to tell him how I feel today.
Good luck with that, just be aware he could report you for sexual harassment if they don't share the same feelings. If they feel the same you might end up with a long term relationship.
