Most Helpful Girl
I don't like to judge, but I feel like this is not the type of guy you should have kids with.
However, the deed is done and I feel like the best thing now is to concentrate on you and the baby. Firstly, all the stress you feel, every time you cry, the baby basically feels all those emotions (hormones and neurotransmitters are passed through the placenta, I guess).
Anyway, you need to learn to be self-sufficient- mentally, emotionally, financially. Plan as though he won't be there when the baby comes, because he is unreliable and selfish enough to put his emotions before everything. The worst thing you can do is rely on this guy, you need to rely on yourself. And if he is there in the end, it's a bonus.
You MUST stress to him that he has to become responsible and clean up his act well before the baby arrives. He needs to prove as much, because an innocent child doesn't deserve to be around disfunction.
Nothing awful has happened yet, you've spotted some red flags that need to be addressed, so don't panic. But I say to every woman, even if you're happily married- learn to be self sufficient. That's the best preparation.
