I don't like my baby daddy

So my baby daddy and I were just fuck buddies and we knew the relationship wasn't going anywhere. I was on birth control and we were using protection so when I found out that I was pregnant we were both stunned. When I initially told him, he pushed for an abortion. I told him I wasn't doing it so he quickly stepped up. I spent the evening with him last night after a month and it made me realize that I don't like him. He's hella annoying and it made me break down in tears last night. I really fucked up by making a baby with this man. It's nothing that can be done about it now but I was wondering if anyone feels this way about their child's father.
