I would pull a credit report to see if there's other things he has co-signed for! So you are telling me he co-signed for his ex-wife to get a truck and you guys had to pay for some of it when she quit paying?? Oh man, you are WAY nicer than me!!! Did he co-sign this AFTER you guys were married? And if I paid for the truck, it would be sitting in MY driveway, not hers!
Then you work 2 jobs to pay HIS daughter's school loan? NOW he tells his 30 yr old daughter you will pay her DAYCARE if she gets a job???
And the EX goes gambling while you work 2 jobs? I don't buy for a minute she can not work.
I'm so sorry for you OP, but you have got to put a stop to this behavior!
You can do this online very quickly and easily, if you have the info, you can do it whomever you want!

That has to be a relief! Now what they are up to, that is a whole different kettle of fish. You and your DH need to be on the same page as to how to handle this and the future. Surely your DH will see NOW, that you both have been taken advantage of. It would hurt me to the core if "family" would not care enough about us to put us through that kind of worry and stress. If that doesn't stop your DH's overly generous pledges nothing will.
