What if I don’t love him the same?

I’m 37 weeks with boy #2 (being induced in 2 weeks)… I have a 7 year old son from a previous relationship and he’s my best buddy and we do everything together. The longer I’m pregnant, the more I seem to be pushing my boyfriend away (father of baby #2)… like everything he does annoys me or grosses me out. What if I don’t love baby #2 as much as my first because of how I currently feel about his dad and our relationship?! What if I don’t love him as much as my first son?! This is really starting to stress me out… I think about it often and feel awful because it’s not this baby’s fault
