ExP broke up with me a few months ago now. Their choice, as much as I've tried to make it work, they're absolutely uninterested (gone NC, defaming me, lying, and the rest). It's been a few months now yet they're still using our joint account to buy items almost daily lunch, travel, dinner, etc seemingly intentional (e.g. will use other cards for dates / drinks).
I know they're having some financial issues which they kept quiet during our relationship (low wage, credit card debts, gambling, etc) and I've offered to help when I found out, still gave them some money for things after the breakup (stupid, I know, I'm still in love). ExP knows I would loan or give them however much they need, and preferrably I would to avoid accounts that I am financially liable for becoming in debt and damaging my credit history. I've made them aware in the past that we cannot let the account go into the unarranged overdraft; we've never needed to, not a sly boast but our lifestyle isn't really expensive and I have a decent job.
AIBU to find it unfair that the joint account has now gone into the unarranged overdraft, which has affected both of our credit ratings?
