Feeling hurt

I feel heartbroken and sad. I was with a high school sweetheart all our relationship I tried helping him out it ended up costing me everything trying to help one guy thinking I could make him happy save him. He abused me physically sexually verbally and financially my self esteem has taken it the hardest so I got pregnant because he wasn't responsible I don't want to get into the details. I thought he would be here planning helping with the nursery and helping with money all he cared about was himself being pregnant he wanted to hurt me I had to leave him but he can at least send money to help! I feel hurt how can going out of your way for some one end up in a disaster. I'm pregnant and scared and slowly trying to peel off the onion skins of the years of psychological battery it's hard can any ladies who escaped from a relationship share your story I need encouragement
