So he borrowed money. Yet again.
You knew he had borrowed it but looked the other way, so you could claim you didnt know if the shit hit the fan.
You know the family is struggling for money, but only now your dd couldnt go to Paris have you decided to get a part time job?
Personally I would want to see bil and dp together and find our what the fuck is going on.
Bil probably didnt want to lend him the money, again. Given it took so long to pay back before? What story did your dp spin?
No wonder no one was interested in the house warming. Dp borrowed money again, to move and you are wanting to shell out money on a party. I bet he has missed a payment too.
To be honest I would be pissed off if my brother kept having to borrow money for totally normal things like moving, never paid it back when he said he would AND pledged poverty, while his partner didnt work. And then they wo3nd a fair but of money on a get together. If my mother was ill, would be even more annoyed at a party being planned .
Imagine if you had have known about the trip and manage to scrap together the money for dd to go? How bad would that have looked?
Your dd is also old enough to understand that the family doesnt have enough money to send one of you to paris and that there are other financial responsibilities that must come first.
Your dp is a dick. He let her feel shit for the day instead of being upfront. But I also suspect you are one of those partners that know your dp is up to something but turns a blind eye, because it benefits your family. Eventually you have to face up to the truth.
Sort your finances out and stop relying in getting money from mils money.
If I were you I would really worry about what your dp will do with the inheritance, if mil passes away. He cant be trusted at all and you need to face up it.
