Search Results: mistakes you wish you could change

Disclosure: There is a very controversial decision in this situation. What is done It's done there is no point in lecturing me. With that being said here is my situation.
So last summer i ended up dating this guy. We really had some chemistry. The only problem was i wasn't looking for anything serious at the time so both eventually moved on. That was ok by me, we parted on good terms, but i found out i was pregnant with his baby a month and a half later. At first he wanted me to keep it, But eventually got scared and changed his mind, But i wasn't sure that was what i wanted. After a long and emotional journey, i desided not to have the child, but i hated him for Not being there to support me or my decision in the end. I would have been ok with never hearing from him again, But a month ago he calls me and asks if we can talk. I meet with him and he looks a mess. He tells me that he made a big mistake and that he really wishes he could go back and change it. He tells me that he really wanted to be with me before and can't move past me. And hopes i can forgive him for walking out on me when i needed him. I basically desided that i didn't want to hate him, it isn't in me to hate anybody, so i told him that if he desided to talk to me, i wouldn't hang up. It would be slow, but i was willing to crack the door a bit and see what happens. Since then, he has been non stop amazing. He brings more flowers at work, drives a half hour to see me on my lunch breaks, and its just an all around great guy. I just don't know if i should trust him. He is really trying. If there wasn't such a bad history i could definitely see a future with him. But it is what it is and I'm completely lost. I don't know if he came back out of guilt or if he really wants me. Anybody have perspective on the situation?
