Cheers for the super fast responses guys, let's see if I can answer some of the questions.
Wondering - I never told him I was only eating once a day - because we live in an isolated location and he was doing the food shop I was reliant on what he brought home, and would have to stretch it for a week - it generally worked out to one meal a day and enough for him to have dinner when he got in of an evening.
Chaz - although we have discussed a joint account on numerous occasions in the 2 years we've been together it's never materialised because he's a master procrastinator and we'd both have to be at the bank at the same time. I've always been a firm believer in "our" money over "yours" and "mine", but I've had to be so firm with myself in these past months I fear I'm rather jealous of sharing what I feel I've earned now...
Yoni - the bills and mortgage are in his name and always have been, but I've religiously paid half up until I left my last job. I'm happy to recommence paying half, and maybe a bit extra to try and plug the dent I'm sure I've made in his finances, I'm just smarting at giving him what will be about 70% of my paycheck, especially knowing his history for impulse buying.
Emma - I completely understand what you're saying, it's something I fell into, rather than him enforcing it. So it's not like he made me go without, I didn't raise it because I felt awful that he was having to support me month on month.
Notsuch - see what I've written to Chaz.
Sole - that's a nice way of looking at it, and that's the way I'm really trying to look at it, when we discussed it this evening I was chewing on my lip so as not to cry, as I was so looking forward to buying a pair of jeans that don't put so much pressure on my tum I feel the urge to pee almost constantly. I know I've put him in a bad financial spot and do feel very responsible for our precarious position now, but I don't feel happy about this. That said I've not the faintest idea of a better plan, and we need to do something.
Katie - not that I'm aware of, but if you add up the shortfall in money from me that he was getting (about 500 a month) plus the pin money he was paying me, I suppose I've cost him about 3-4 grand. Which makes me feel awful.
Right hormones are now raging, I'm going to go and have a quiet cry.
Thanks for your input ladies.
