Asking for a friend, who's really struggling, emotionally.
She's a lesbian, and began dating a woman on her degree who displayed interest in her, but seemed unable to commit to anything official. Let's call the woman A. A came with the whole "I'm messed up. I have issues" narrative. From the start, she's been inconsistent - saying one thing (I can't commit), but then doing anything (spending all her time with friend, being super friendly/jokey/flirty with friend, being intimate with friend). What she has been consistent with, however, is her pattern of behaviour - getting very close during term (spending endless days at friend's flat, being intimate, opening herself up to friend) and then backing off and demanding space (sometimes even breaking the whole thing off) during any kind of holiday or break from university - and becoming really quite cold, vile and emotionally abusive during this period.
Friend reckons that A has BPD, and I don't disagree. Friend is really struggling to deal with her feelings in regards to A. She knows that A is terrible for her and that she should stop hoping/waiting for A to 'come back', but she feels unable to due to the intensity of her emotions and feelings of longing. Friend already struggles with depression, co-dependency and so forth. Also, the fact that they're on the same degree makes the whole thing all the more agonising for friend - she has to see A 3/4 times a week!
She feels totally unable to move on from this, or break away from A's pattern of abuse.
Any advice would be appreciated.
Thank you!
