Having a hard time😢😢

Hi ladies, so first off I'm 9 weeks pregnant 2nd i cheated on my bf( he knows were working through it as a couple we are still in love with each other and he has forgiven me I hate myself every day for what I done I'd sell my soul to take it back... But my problem is my bf feels like the baby isn't his but a part of him feels like it is. I got pregnant around the same time it happend but the man I cheated with wore a condom and me and my bf has had unprotected sex all around the time I got pregnant I just feel like my bf won't be as close with this baby as he was with our first when I feel like it is his
