Backstory: DM has a lot of money. Her partner doesn't work, their kids go to private school etc. Me and DP don't have much money, we get by ok but currently have quite a bit of (manageable) debt. We got a loan from my mum earlier this year (to pay off debts) and are still paying her back.
Our 12 year old car has just broke down and is basically more hassle than it's worth. We both agree we need a new car. He wants me to ask my mum for a loan. I don't agree, as we are still paying her back but mostly because I feel really awkward but he's being quite pushy about it. I think we should just get it on finance. His reason is because DM treats my siblings differently I apparently need to address this. I agree with what he's saying but I just hate asking for things. She knows we don't have much and I feel like if she wanted to help she would.
Am I right or do I just need to swallow my pride and talk to her?
