My girlfriend is BPD, we've dated 7 years now
Basically it's cyclical
>Normal relationship, things okay
>She gets cold towards me, sex becomes rarer
>Eventually she cheats on me (and it's always in some extravagant way, one time she fucked 5 different guys in 2 weeks)
>Comes crying back to me
>I've always forgiven her since I do love her
>She's super loving and perfect gf, fucking 3x a day for a while
Although I think she's getting better, she hasn't cheated on me in almost a year
Advice: don't fall in love with someone with BPD
