I have a boyfriend but have fallen for lesbian coworker

I have a boyfriend and baby daughter and felt happy in my relationship until recently. I have become attracted to a girl I work with who is gay. She is also in a serious relationship. At first it was just a crush but now I think I really like her. I am bisexual although haven't told her this yet. I think she also likes me. I feel for some time now it has become something unspoken between us which we have both hinted at but not acknowledged. I don't know if I should tell her how I feel? Even to say while we are both in relationships nothing can happen? I work quite closely with her and don't want to make things awkward between us or potentially ruin a possible friendship.

 

Thanks, that is good advice. I hadn't really thought about it like that - how I would feel if it was the other way around. I think I have been focusing a lot of my emotional energy on her rather than my boyfriend, if that makes sense.
