Please help me desperate for advice

So I have a daughter who is 13 months old. I am currently 18wks 3 days pregnant. My boyfriend is Chinese and I am English. We sometimes really clash with our views and expectations of each other. We found our we were pregnant with our first child very early at the beginning of our relationship we were just together just 5 months at the time. We had been living together from the start we were very full on. He promised me we would get married and I was foolish to believe him. Anyway I moved away from my family 1hr 30 min when I was 17 and he was 23. I found out I was pregnant when I got there. I moved back home before the baby was born about 38wks. He hasn't forgiven me for moving back but I had to the place we were staying had 3 flights of stairs and I had very serious hip problems at the end of my pregnancy. I just couldn't keep walking up the stairs. So I went to stay with my grandparents their house has a downstairs bedroom so I could avoid the stairs.

He was working for his cousin and the job was very easy and the money wasn't bad. Another reason I moved home was because the hospital is closer just 30 minutes away but when I was before it was 2 hours. So I stayed with my grandparents after the birth and I decided to move closer to them and get my own house which I did. He just couldn't forgive me he said that i abandoned him and that i never followed the plan but I had to do what was best for me and the baby. I need my family to support me I was just 18 years with a newborn I had never changed a nappy before or breastfed.

He changed jobs to be closer and he had to move around jobs for a while and now he has a really good job really close by. The house I picked were no good in very poor condition and I picked 2 of them in a row. So I'm in between living at my grandparents and living at the house I am now waiting for my tenancy to end. My auntie is going to give me her house to rent so soon I will be able to probably do the family life I wanted. In the house i live now everything grows mold and its damp i just sleep there and when I wake up I leave. So it hard to get chores done.

So I can't take contraception as my period is never ending and the only one that's works for me I have to be about 3 stone (42 pounds) lighter than I am now.

So I ended up getting pregnant which wasn't really prevented as I was wanted my children close in age anyway. Well this pregnancy has been a lot harder than my first like I have had a lot of bleeding. I'm not as confident as I was before. I am always frightened of something going wrong.

Well for the last 3 days I've been pushed to my limits. Severe sickness and diarrhoea and I couldn't eat or drink anything. And I have still had to look after a toddler on my own and getting occasional help from my grandparents.

Well my boyfriend works away from home be sleeps at his job if be tired which is fine. Well he asked to come home tonight he finished work at 11pm and I asked my grandad if he could get him which he agreed to. My grandad got there and waited 30 minutes for him and he wouldn't our calls. So my grandad left he was tired and not in the mood to wait any longer.

I told him off for being so disrespectful to my grandad for not waiting and being ready. Well he blows up saying he knows he is wrong but he wants nothing to do with my family and doesn't want to step foot in their house again.

My grandparents raised me and have been a big help with helping me raise my daughter and helping me out when I have been too ill with morning sickness to look after her.

I said he was being unreasonable and that our daughter loved her grandparents and that I refuse to separate her from them because hes been pretty and childish. he said he was tired of me and the relationship which felt 10x worse because of my pregnancy hormones. So I'm crying and telling him he ruined my life. I do not regret my children I love them but i wanted to go to university and get finally stable before having children but he was so convincing he would support me and love and cherish me for the rest of my life I trusted him.

I begged we give the relationship another chance because I didn't want my daughter to be torn in two at such a young age. He said he would try.

I honestly am so stupid that I still love him but I'm pretty sure he says he loves me to continue to see our daughter.

I never imagined my life like this. 19 years old the single mother of two children. I wanted more for my children and for myself. I know I shouldn't have had my children so young I was foolish but I love them so much.

What do you think ?

UPDATE :

I forgot to add I do not blame him souly for having children. I had children because I had always wanted to be a mother and I loved him. After my daughter was born I attempted to go back to school but he did not help me when I did. He would get angry at me when i tried to do my homework and I would hand him the baby. He ruined her sleep routine that I had put in place for me to go back to school and he wouldn't wake up in the night to help me even though he was the reason her sleep routine was messed up. I begged him to listen and understand that I needed to finish school but he kept telling me to quit that I should just be a mother. In the end i was so behind i had to quit. I've put all my love into my children and I do not blame him for having children. I wish I had been more realistic before hand.

I blame him for lying to me. For choosing words that he knew would hurt me the most. For not caring how our growing baby is feeling when I am this depressed. My family all begged me not to choose him and i told them all they were wrong that he loved me, that I would get married and live the life I wanted and I'm disappointed in myself the most.
