Just need to rant a bit. Both DP and myself are self employed and to tbh DP is just so rubbish with money so I would never had joint finances with him. ( he is always overdrawn, regularly fails to make payments and often fails to pay what we have agreed. Anyway DP wrote a check last week that bounced and obviously the other person was furious. So although not happy I said I would lend him the £200 so when person represented it it would be covered. Anyway he swans in last night armed with a few bottles of wine and fags and said he had been to garage to put a new tyre on his van. I don't know why but I am really cross, am I being petty?
