I don’t want to move out

So my ex gf  wants me to move in with her when she gets her own place. I don’t want to move in with her because she has been kicked out of ever place she has lived. I’ll be dammed if I become homeless again.  I’m trying to get back with my ex girlfriend. I have always cared about her. The reason that I broke up with her is because she wasn’t ready to be with me. She was hung up on her ex. I’m not ready but I might leave soon anyway. Idk  why
