Basically in last year at uni I lived with one of my best friends in a 2 bed flat.
Her dp moved house to be with her relatively early on (this was always the plan) and proceeded to live in our flat for the next little while (this was not the plan), and to cut a long story short, I was full of "no problem at all" at the beginning but then started to feel a bit very used...
I liked him but started to get a tad resentful of the fact he was ALWAYS there and not contributing to bills, despite often being in the living room etc. and basically treating the place like his own.
Even after he "moved out", he still generally stayed over most nights and cooked there.
After a while things got better but then worse (long story which I won't go into) until they then broke up and the place was finally half mine again!
I like her a lot and she is so close to me in many ways; but sometimes I actually still find myself brooding over the injustice of it all
I would never in a million years do this to a friend and expect them just to take it!
As I say, she really is a great person. But AIBU to be nervous she'll pull a stunt like this again?? Btw we don't live together now and won't be for the foreseeable future...
