<human>: Hello R-advice I'm in need of some assistance. Please help.

I met this girl 10months ago and its been on and off an amazing relationship the sex usually is great minus some random times where she gets into a routine, the problem is that sometimes she is extremely bipolar and freaks out and runs to her mom who constantly bashes me saying im unproductive and I free load off of her and generally dislikes me.

normally this isn't a problem it does get to me but since I have spina bifida (luckily able to walk on my own and such) have troubles holding or even obtaining a job and I constantly feel like im holding her back or ruining her life.

She has gained 40lbs since I met her ( which I dont mind ) but she always calls herself fat, ugly and what have you and her mom even says it to her constantly saying how she is lazy and not trying to get a job. 

It's really all putting a strain on our relationship and we have been fighting more and more. Please help me? I do love her

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I'm disabled, feel like im holding her back... she is bi polar and has a evil mom who thinks im a worthless free loader and constantly tells my fiance she should leave me and love isnt enough for a relationship.
