<human>: So about a 8 months back, I lent my gf of 3 years some money to help her pay for the rest of her school and other stuff. At the time I was working at a job in another city, but was already set to come back home (not because of her, but because I had another opportunity lined up there).

At the time I said something along the lines of "this is my half of the first 8 months' rent when I come back." Even with the money I gave her, she still has loans to pay and isn't making enough to pay me back if I wanted her to. This is complicated by the fact, that she got a slightly nicer apartment in a  big city because I helped her out, which she pays a lot of her income to afford by herself now.

So anyways, I feel like we've both changed during this LDR, and that I definitely don't want to be with her anymore. The problem is I also want her to pay me back at some point. I won't starve without the money, and I could afford to move in to a cheaper place by myself but it's a quite a bit of money and would help me out if I had it.

I was planning on moving in and just pretending for a while, but I'm about a week away from that and it's just starting to seem like a terrible idea. She would not be ok with us living together if we aren't dating, and will probably just not pay me back if I broke up with her at this point.

I guess I'm just wondering what I should do. A friend suggested I live with her and see if things go back to how they used to be, while another told me I should tell her now and just take the loss.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Gave girlfriend money we both assumed would be rent for when we lived together, changed my mind, now want to get out of relationship without having to give up money I gave her
