bpd/bi polar

Has anyone ever been with someone who has bpd/bi polar ? 
I'm not saying I have a problem with them. 
I'm just asking if anyone has ..
I have been with my girlfriend for 4.5 years and after hurting me so many times , it's hard leaving .. she won't let me.
But she's a massive sex addict .. and always gets mad at me if I'm not in the mood. Everything is about sex.. makes me feel like it's all im good for ... just want to know what stories are out there.
I feel like I'm not in love with her anymore .. the sex is also not that satisfiying. She can't get me off unless I do it myself. 
And also saids random Shit.. like in the morning when we woke up.. I said go make us a coffee babe ( since I do it every other day) and her reply was " lick my vagina" .. or she asks for sex all the time instead of jus doing it .. I don't know how much more I can take
