Pregnant and alone

Senetha • TTC
Idk what to do...I'm 41/2 mo Pregnant. My fiance does not want our baby right now b/cuz of what he claims a financial burden. Prior to me getting pregnant we were trying every weeks 2 get pregnant he wanted this baby Even before myself. Which is why it hurts me that he wants me to get an abortion. After a while he told me he would b here for me no matter what I chosen. I chose to keep the baby, and now he texts me less and less and doesn't check on me. He says he is staying away until he can handle the situation. I didn't get myself pregnant. I feel so lonely and I'm sick of crying. I'm thinking of leaving him but I don't have much family or support. He is all I have. What would you guys do if u were me??
