I'm so sorry to hear the pain you are in, Raenesia. I've been there, with my first husband. He made so many promises, and told me so many times how important I was to him, and I kept hoping. It was a mistake, and I'm so much better off without him. But it took me a long, long time to learn to let him go. I hope you will get there faster.
I'm really concerned about your further hope that your baby boy will be the little man to love you unconditionally. Those hopes will accomplish one or both of two things:
1. You'll be disappointed when you learn that a baby NEEDS you unconditionally, and it will be a long time before he's able to love you just because you are a person worthy of love. And when his needs for constant, exhausting care clash with your needs for sleep, support and love, you might both suffer for it.
2. If you make him the center of your world and use him to meet your emotional needs, it will place demands on him that no child should have to meet. To whatever degree he tries to rise to your expectations, he will have to ignore his own natural needs for nurture, support and freedom. This is not fair to him, and will not be fair to you, either.
So I hope you will seek out counseling. It will help you find alternative ways to meet your own needs, take care of yourself and your child, and, if necessary, let go of the immature man who has impregnated you.
Best to you.
