<human>: Hi, this is my first post here. Throwaway just in case.

I [M23] broke up with my girlfriend [F24] 2 years ago. Three months before we broke up she starting living at my parent's house due to financial strains. I had been moved out of my house for 4 years at that point and my parents were fine with it (she took my old room).  

Fast forward 2 years later to today and she is still living there. She has formed good relationships with my mom, dad, sister and brother. My mom and dad are kind people and just want to help her out. They all like her and she pays rent which helps them out to a degree. 

Occasionally, she will be around the house when I visit and we make small talk, but not much. She has pushed trying to remain friends since we broke up and I've tried, but it has never worked out. I just can't be friends with her and she has never been able to accept it.

Every time I see her it just brings back memories I'd rather forget. I feel like I should be over her and not care anymore, but I can't help getting upset/emotional when I'm around her.

She's struggling, doesn't have any real family and I honestly feel bad. I don't want to kick her out if she needs it and the rest of my family are okay with it, but it's obviously hurting me emotionally.

Has anyone ever gone through something similar to this? Any advice?

Can you condense the text into three sentences or less?
