Quite long winded, apologies. The father of my unborn baby decided to leave, wanting nothing to do with baby. While we were together he gave me £150 as my wage and housing benefit got screwed one month. I immediately refused it, sent it back and he sent it back to me again, insisting I accept it. So I did, he said to pay him back when I have it and that he wasn't bothered if I didn't at all if it came to that. Fast forward to him deciding to leave, he demands the money back, in what I can only say was a tantrum. I didn't have it all, so I sent him 40 which was all I had in my bank account. He calmed down, sent it back. He then decided he wanted nothing more to do with me, demanded I post his things to him, which I did. Haven't heard from him in nearly two months after he told me that he felt like hurting himself and I told him to seek help. Today I recieved a message staying he's waited long enough, he wants his money regardless of 'what has happened', and to not bother replying as he's blocked my phone number. It's almost Christmas, I don't have the money to spare, I have a four year old to support as well as myself and need to buy things for the baby. I feel I need to pay it back. I just can't afford it. What can I do?
