Rough time.. Need words of reassurance

I'm a 17 year old mom. Although I didn't plan this, I'm grateful for my blessing. I'm 15 weeks pregnant and the father of the child is very emotionally abusive. He is a loving man and he is a good person but he and I aren't getting along. In the beginning I noticed he was kind of "crazy". He is 20, so he is older than me so I always assumed the age difference brought that sort of possessiveness for him. I grew up with divorced parents and I hated it, it was very hard on me and my siblings. I don't want that for my child, I know he doesn't either. I'm starting to realize how I screwed up my life by not taking precautions to prevent a child and it's getting to me really hard. Prom is coming up for my friends and I just want that life, happy with my friends and summer is soon too. I'd love to be that teenager again. Not a mother so soon, not the happy life I wanted. Things are just very hard and I need lots of help along this journey. Keep me in your prayers ladies! I appreciate it a lot.
