Should I stop communicating with the father of my child?

I have met my ex boyfriend in the Christian Website and we became good friends until we became we.. When he visited me in my country and got pregnant I felt disappointed with him. At first he wanted to abort the child but I fought for my baby. I never felt to be treated as a real girlfriend. during the past 3 mos of staying here, he preferred to be with his friends and stayed with the family of his girl friend (not a lover). HE wasn’t there when I had bleeding because my pregnancy is critical and whenever I needed him. I have decided to forget him after that. On the day I was a about to accompany him in the airport as he was about to leave he told me he wanted to stay with me even for 3 days. I thought we would be fine. 3 days became ok. When he flew to thailand for another tour he had debt to my brother because I helped him to buy plane tickets for his tour and promised to pay me not included other debts of 390 pounds. It took him more than a mo to pay and I was in the depression because I was the one facing the shameness to my bro for him not paying that. Not only that, he hurt me when he said we better be friends because he’s far so it means he gave me up already just because of the location. When he went back to UK I tried my self to forget him. I lost my job but with the help of my family and brother and savings, I am trying my best to support my pregnancy. We became ok when he was already in the UK, he’s still unemployed. before he said he wasnt happy for the baby but when he went home he said he’s happy but not yet told to his parents and family about this and it hurt me because im 6 mos already. Last time, he asked me to send money to his friend here. He wanted me to send it asap and got from the savings that he left for the baby. It’s our savings of only 141 pounds left. I felt sad because he even care for the sake of his friend than me and the baby even if he knew I am in a critical condition and money is not enough. He told me he will replace it when he got job but he’s having hard time to find job so im the one looking for a way to make money to add in our savings. I made him to promise that would be the last time to send money to that girl but he didn’t promise me.. because for two mos time he already sent money more than I have already to a girl I dont trust. HE just said his friend need it for education but I feel he’s giving more importance to other people than to his own flesh and blood. We had a and argument because of this and to end this up I still sent the money. I explained to him that when he got the job he better pay off first his debts in the UK. I wanted to stop communication with him because I feel not so important for him. I told him I will stop but he doesnt want to. I also doesnt want my baby to lose a dad. HELP ME OUT. I do not know if he’s just so insensitive or im just martyr for everything. Because of this, I couldn’t sleep so well. I do sometimes wake up int he morning and cant stop thinking the bad things he did. Pls help me. This makes me feel depress and affect my condition more.
