I had an abortion and lied to him about it, but he found out.
Why would you lie to him about something to severe?
I didn't want to tell him the truth, but it ended up badly.
I understand you were afraid, but you need to be honest with your boyfriend. You can't have a real relationship of there are lies.
It's over, he's not going to forgive me and I regret it.
Well if you've tried apologizing and he won't forgive you it may be best to move on. Take these lessons and learn from them otherwise it was all for nothing.
