My SO and I have been together for almost 4 years, I moved in with him around a year ago. As his job is much more demanding and he earns a significant amount more than me, and has fairly small outgoings compared, we agreed that he would continue to pay the mortgage bills etc as he was before, and I would help out with shopping etc and pay for holidays. This would also allow me to build up a bit of a nest egg for security as moving in was a big step for me as I've previously been left homeless with nothing because of moving in with someone abusive.
This was going fine until I realised how irresponsible he is with money, since April he has managed to spend over 70k, we have been in a pandemic and so haven't been out much and I have fully paid for the 2 holidays we went on so I really don't know how he's managed it but also feel like because he covers the bills it's not something I can question him about as it's his money.
My issue though is that at the end of November he told me he had hit his overdraft limit and could he borrow money for a few days. I sent him 2k. He received 7.5k at the start of December and paid it back but then a week later says he has hit his overdraft again and could he borrow more. I sent him 1k to tide him over, I sent him another 1k last week that he asked for and then he turned around to me 2 days later asking for another 1k. I sent him 500 as I really wasn't comfortable with sending him more when he seems to be burning through it. I've just heard him on the phone to his friend saying how he's got £500 left and he's just come back from shopping and must have spent £100 on dinner for tonight and bottles of wine when I've said I'm running out too and we need to take it easy.
I actually have a lot more in savings but I don't want him to drain me out and then not get it back and I feel like he's still trying to have a lifestyle which we obviously can't afford it at the moment. I feel bad that he's struggling and is the main bill payer. Am I right to feel like this or am I being selfish and should I be giving him the money he's asking for when I'm essentially living in his house for free?
