Not sure what to do...

This is my second pregnancy & I’m not as happy as I should be. I just feel like I’m alone in this. The father isn’t ready & says he’ll be there, but it’s no secret he doesn’t want this baby & I don’t want him around just because he feels obligated. I’m depressed & I just want to enjoy my baby boy. I’m 20 weeks & 1 day & feeling his precious little kicks, I just don’t want to be sad anymore.
