You need to be strong gal. And make sure that he pays for it.
No use caring or respecting someone who doesn't even give a bother about you. He dont't deserve your attention and heart pain.
You are still young and still have a long way to go. So dont't worry too much. And I can tell that your mom supports you as well, so at least you have someone to lean on. Being a housewife for 5 years doesn't mean that you wouldn't be able to find a job which can support both you and your son. Just be strong. You'll find a much better and more deserving man.
