Once he becomes a father, his girlfriend/wife and kids should always come first and I'd hope his family would understand since I'm sure his dad put his mom and him first.

no. when he makes his own family y'all should come first.

I'm not sure what your asking but I'm having problems with my boyfriend on something like that & I put my foot down to let him know that we are having a kid and bills to pay & those come 1st !
