man walked away from his mum and me

so I need advice me and my man are difficult atm because he's bad at financial things and we don't live together so he can pay his debts but his flatmates use him and he spends his money on rubbish, now three days ago I had enough I have three kids and he asked to borrow money. for the past two months I've bought almost everything for the baby to help me and him. when he asked me for money I snapped I got fed up I just found out I have placenta previa I almost died with my second with same thing and his friend told him not to check up about it on Google. now this is his first lil one so he doesn't know all the lingo. He never helps me with kids or sits them so he doesn't know how hard it is he works alot and when he comes over he is tired within 3hours and I feel so frustrated I'm doing all of it really. so when I pulled him up he walked out but only after he came over to pick his car up and when he seen how crappy I was he decided to moan at me about my parenting because I snatched a controller out of my daughter's hang because she was ignoring me 5x. then tells me to appologise to him because I went off at him for telling him to leave. then when his mum last night actually brought up problems me and him fell out about at his brothers after party I was so relieved! my man doesn't realise how hard this will be and I got fed up. so basically after his mum pulled him up for unrelated to me problem with his money seeing as he asked for a loan off her aswell. He didn't like what she had to say and he walked out and left me at 2am at the party. I have never felt so abandoned in my life. so after he left me there I made my own way home alone even though I was told to be watched for 48hours after a fall and he eventually spoke to me at teatime and said "hi" I just ignored it. am I being daft?
