12 years ago when I was single I bought a gorgeous old 2 bedroom flat that was a bit rundown in a not so nice area. I flatshared with my best friend (lets call her Becca) for most of the time I lived there and we tried our hand at some DIY/restoration and had the place looking incredible.
My DP and I bought a house 3 years ago and before that he lived with his parents. We're not married and we have a joint bank account that all bills come out of with our own separate savings and current accounts.
Becca and her DH split a few years ago in pretty awful circumstances and her and my goddaughter (4) moved back into my flat. The rent is the same as it was when we lived together.
My DP has become quite fixated on this flat. The run down area has now been fully gentrified and is one of the top places to live in the area. He told me that the going rate for rent is now 5 x what Becca pays. He's also looked into recently sold prices and told me what 'we' could do with the money if I sold the flat now. DP has a lot of excellent qualities but he is extremely greedy when it comes to money.
It's become a really touchy subject for us and he keeps saying that I want to keep the flat because it reminds me of my 'wild single days' and that I'm not fully committed to the relationship until I let go of the flat.
YABU- sell the flat
YANBU- keep the flat as you'll need it when you leave him (said in slight jest)
