I don’t know what to do.

My fiancé left me after 5 years together... I’ve been so heartbroken. I’m moving back in with my mom, so I can save $$. I wanted to leave far away, or party the summer up to meet new people & make friends since my world revolved around my ex- fiancé. Was going to go back to school. But I just found out I’m pregnant. He wanted me to get an abortion, told me his life is ruined. I don’t want to get an abortion because we were TTC for 7 months. The month he broke up with me was the month we stopped TTC. We hooked up about a week after the initial breakup (we live together) and got pregnant. I’m 5 weeks 5 days and broken up for almost two months. Our lease is up at the end of the week, So I’m moving into my moms but I’m so scared. I thought i had this plan after the breakup, and now that I’m pregnant I’m scared. He is supportive of the pregnancy now, but doesn’t support me at all. He refuses to be kind to me and it hurts so bad because I still love him. I want this baby, but I’m scared I don’t have the right resources, I don’t have a partner to be by my side, & I’m scared I’ll be alone forever. I’m scared to see him party and live life while I’m sacrificing my whole life for this baby. He wants to be there... but it hurts to know we’ll never be a family and I don’t know if I can deal with the heartbreak of seeing him all the time, especially when he gets someone new. I didn’t finish school, I’m scared I can’t give this baby a perfect life. But I do love it and have always wanted children. But not like this... but I don’t know if I could live with any abortion. I really need some advice.
