To blooming well refuse to pay this debt and tell MIL to p*** off?

[MetalSian]

About a year ago my DP decided to borrow £2600 from his Uncle to buy a car... pretty much behind my back.

He also increased my overdraft to £750 and took out £700 as a deposit for said car.

Now a year down the line I am being told by his mother that she needs to talk with 'us' about paying his uncle back.
DP is supposed to be paying back £50 a month but was unemployed and only been in a new job for a month so money is tight =/.
Apparently as we are a couple we are both responsible for the money.

To which I replied:
'Please don't tell me I am responsible for a debt that I had nothing to with and had no choice over, I am not going to argue about it, please do ring DP and talk to him about it.'

This carried on for a little while longer with her not getting the picture that I refuse to put any money towards something I had no choice about.

And the last thing I got was: 'will talk to u both together cos im sick of the divided loyalty between families here' (Yes, she doesn't manage to type in proper English).

AIBU? Should I be responsible for paying back this debt as well?
Fed up of being piggy in the middle and everyone moaning to me instead of talking to DP [Angry].

Call the CSA

Make sure you have NO financial ties to him

Dry your eyes, spend time with your parents and give yourself time to grieve for a bit

Then give yourself a massive pat on the back and celebrate making the best move of your life!!!

If the uncle can arrange the loan without talking to you, he can arrange to get it paid back without your involvement too. If you bail him out now he won't learn the lesson and will do it again.

Don't bail him out.

Here's an old management tip. When the mother in law goes on, use the stuck record technique.

You: Im sorry you feel that way but it was arranged without my involvement see DP.

MIL. BLAHBLAHBLA

You: Im sorry you feel that way but it was arranged without my involvement see DP

and so on until she runs out of steam. :-)
