I’m lost and angry

I’m 13 weeks pregnant and I never expected for my pregnancy to be an unhappy one. I went through my first pregnancy alone but I was happy. I then got back with the father and I thought it would be better because he promised me he changed. Now he’s not providing nor does he care about us. I constantly cry because I don’t know how I’m going to make it with two kids. I keep thinking I’m not going to be a good mom. I just want the best for them. Life is already hard with a 2 year old. I love my children and I want to become stronger and stop depending on a man to care and save us.
