My now ex-girlfriend is pregnant - I knew I needed to come out when she told me.

So, I'm 31 and I've just broken it off with my girlfriend because I think I'm gay.I did it because she's pregnant. Yeah, that's the reason. I knew that I couldn't live a lie. I knew that if we keep the kid that I didn't want to ask it to believe that lie.My girlfriend is devastated, of course. I was never in love with her, but I desperately wanted to be. I desperately wanted this lifestyle, but I know it's not what I need to be sane and happy in life.So I did what I thought was the brave thing, and broke up with her after we found out.I've asked her to get an abortion, and she doesn't think she can do it.I've been running from this for a long time. I've been trying to deny my true feelings for a long time, and I frankly don't feel emotionally equipped to cope with a kid - or myself, for that matter.I feel like I'm starting over. And to deal with a kid on top of all that? Difficult, to say the least.I've made a huge mistake. And I've hurt people I care about. I feel I have a lot to atone for.I'm scared shitless - I don't even know how to start this. I'm not even totally sure I believe it. I liked sleeping with women. But I never felt my heart was in it. Where is my heart?
