I don't know what to do!

Me and my partner been dating for 3 months now we got pregnant back in August. the time he learns that I'm pregnant all I got is a shock from him while I was excited. week after week he has been saying he hope that it's not his, he hope that it's the other guy, he is stressed over this, his life is over, etc. I've been hearing it for the past 13 weeks now (I'm 15 weeks now) an it's stressing me out. I've been telling him let me raise my child but he keeps saying that he's not that type of guy, he don't want me to do it alone....but I'm trying to make him happy trying to give him the opportunity to live his life on how he wanted. but he keeps saying no. But I don't know what to do in this situation I don't want to get rid of my baby so that's never on my mind. I just need help in this situation
