Pregnant by ex.

I have a boyfriend but just found out I’m pregnant by my ex, so before my boyfriend and i got together. My ex doesn’t want it. My boyfriend and I started dating 4 weeks ago. He said he doesn’t want to be involved in the decision making because it’s my choice, but he’s with me no matter what and he won’t leave. He did say he would be there for the baby and stuff and be a father figure. His best friend (who is also my best friend) and him were talking and he told her he loves me and wants me and doesn’t care what I choose, but although he’ll be there, it’s not the same as if it was his. He said he won’t treat the baby differently he just wishes that it was his baby because it makes a big difference to him.

I understand where he’s coming from. But I really don’t know what to do. I know I’m keeping the baby. But am I wrong for feeling a bit upset by his comments?
