First 2 things:
I did nothing to make him feel the way he does.
You most certainly had a part in your marriage's break-up.
Sometimes I wish i was a man so i could have no feeling and no care in the world.
You have a very distorted and unhealthy understanding of men. Your husband's infidelity and lack of commitment should not make you resent all men. That will only hurt you in the long run.
Now, stop texting and calling your husband. I mean stop NOW.
I'm very sorry you're going through this. Sounds like your husband is bailing on his child and marriage without at least financially making the right decisions.
He has to support his child for the next 18 years. That's the law and it's not hard to make him oblige.
As for your marriage, there's little you can do right now except allowing time to clear up some of the fog. In the meantime, ensure your husband does what he's supposed to do with regards to the baby's financial well being.
You also need to accept that you might have to manage your own financial needs. If that means getting a job or a 2nd one, then that's what you do.
Be strong. It's still too early to predict where your marriage is headed. Give it a few weeks before making sudden decisions. Be civil with your husband and allow him to have a part in your baby's life.
