Can't win in life.

Dated a few girls before, for the first time I actually fall in love with someone. My girlfriend or whatever that is loves me very much as well, but she has a new co-worker who is a lesbian. Initially my girl told me she was bi, but that didn't matter to me.

For the past week she has been distant and told we needed space but we need to be talking to each other etc which makes no sense, then later she tells me that she has a co worker that she is very attracted to and that girl made moves on her and my girlfriend has a thing for her.

For the first time in my life I actually fell in love with someone because I have always sheltered my emotions knowing that some shit like that might happen, and when I finally open up, it really does happen.

I'm so lost I haven't slept in the past 3 days. My girlfriend is like I need to evaluate and see what I really want, do I want to stay with you or leave you essentially, and that is heartbreaking. Usually I wouldn't put up with any bullshit like that, but I guess love is blind and stupid.
