I'm with DP for 16 years. He had a female friend from Uni who was a bit hard work. She had a lot of male friends back then but fell out with all of them one by one. Those male friends are still friends with DP.
She went abroad for 10 years and returned home and started inviting DP to hang out. She's been generally nice to me and for a while we forged a friendship but we're just too different. I would describe her as having "main character syndrome". She attracts a lot of drama, doesn't want to know about my life/opinions/successes and likes to laugh at me if I get stressed out about something, saying I'm hysterical. Meanwhile she's constantly having mental breakdowns and needs everyone else to take care of her.
I'm fed up with her tbh.
She generally only messages my DP. She says this is because she sees us as a unit, like the same person.
Last week she said she wanted to speak to my DP about something in private. He asked if that meant no Watdidusay. She responded "Private."
DP said he didn't feel comfortable excluding me and she accepted that he didn't meet up with her. She said she saw us as two individuals, and it was normal for her to have some private conversations with him just as she would have some private conversations with me where DP would be excluded. This has never happened and seems to go completely against what she's said in other contexts. I feel like she manipulates things just to deal with the situation.
I'm just generally really angry about how she behaves towards me. DP is fed up with her too but feels guilty about being mean to her.
We're still being polite to her but I don't know if I would be able to outwardly justify my anger. I'm just leaving DP to deal with it and I'll fade out and not have much to do with her.
Am I nuts?
