<human>: Can you provide a brief rundown of the text in within 3 sentences?

I had been with my boyfriend for 7 years and we broke up 3 months ago. There are many issues, but the main is that we live together and I pay 70% of the bills. He was unemployed for 2.5 years (lost job shortly after we moved in together) and then last year got a part time job. When we broke up I said that I would give him back his half of the security deposit ($400) on our place as I was signing a new lease without him. I specifically said I would give him the money if it would help him find a new place quickly and he needed the money to get started on his new life. That was  3 months ago. This week he is supposed to move into a property owned by a relative where he will only have to pay utilities, not rent. We got into a fight over some food of mine he ate and paying me back and he said "Does this mean you aren't going to give me the security deposit back?". I thought by sticking around for 3 months he would have realized I am not going to give that back. Reddit, do I owe him money?
<bot>: BF and I broke up. He wants money he says I promised him, yet my promise was conditional on him moving out quick.
