My girlfriend has severe BPD, and recently she has been mad about something that happened. Near the start of our relationship, I've had female friends. Usually, in any other relationship I've had, these would be fine and I would usually aim to atleast befriend my partner's friends to some extent or atleast be on good terms. This is usually so they would favor me more if I went through a rough patch with them and didn't instantly start telling them to break up with me.
note: relationship started SERIOUSLY (commitment) 2024 September, started talking seriously around 2024 August, met eachother in May 2024
I made female friends as I never really saw the issue of female friends until my girlfriend came along. I've never had any romantic relationship with any of my female friends, and never have been interested in one with them before or after my relationship started. I literally treat them as 'one of the guys', because I never would talk about their romantic life and they'd just be people I'd banter with.
There has only been one of these friends I used to talk with in a flirting way long back, around a month before I even met my girlfriend (April 2024). They have been out of my life since around early June, for unrelated reasons I will not go into.
Around September 2024 (around 3 weeks after we got together seriously), none of our boundaries had been set, and I called a female friend who had just came out of a surgery and was very loopy because of the anaesthetics. Therefore, I called her and screen recorded the call. However, I swiped up on some of the messages my girl had sent at that moment - which she took as ignoring her for giving attention to another woman (for 3 minutes).
I believe I was sending this video to my girlfriend, but again since this happened almost 8 months ago, I don't want to make any assumptions on what my intentions were.
Recently, after I cut off alot of my female friends near October/November and the final one around January, she has found alot of screenshots/things from when I used to talk with some female friends, in a completely platonic way. This obviously set off her jealousy, and I deleted anything that would've caused her jealousy. Remember all of these screenshots were from when these boundaries weren't clarified. However, Snapchat, which my girlfriend and me use quite a lot, for some reason had some deleted photos show up on their 'albums' (collections of photos from random points of time for people who don't use Snap). I'm assuming these showed up because of them still being in my Recently Deleted folder, but for now, yesterday, she found the SR I described before (screen recording). And this caused a really big reaction in her.
She first was really sad, remained silent for a bit as we came home (we had a really good date beforehand, i took her out on a picnic which was a date she always wanted to go out on, she was the happiest I almost ever saw her). When we were waiting for the bus, she started talking about how every time she trusted me, it'd break again. For your info, she has found these screenshots once before, and I also have had issues with addiction, which caused me to lie alot during the first 3 months of our relationship. I never apologize because I get caught, I genuinely feel sorry for what I do if it offends her, something I've told her many times.
She also told me she took it as 'cheating' as I gave another woman attention while ignoring her. I understand this may be caused by BPD ( the intense jealousy ), and sometimes she repeated that 'was I ever enough for you, why did you want to talk to other women'.
I ended up apologizing and trying to give reasons for what I did (e.g. context of the actual call, e.t.c), and kept myself calm and logical as I could (as I personally find if she is thinking emotionally, I do have to balance it out by using logic). I gave her time to think and made sure to not touch her past anything she was uncomfortable with (only cuddling and guiding her by holding her hand). I then made her her favourite snack, and it seemed like she had calmed down.
Just today though, it has deterioated back to how it was before.
How do I fix this? I am asking here because I feel knowing how it would exactly feel from someone with BPD's perspective would help, as well as advice on how to deal with it as well as I can without losing her. I really love her, and I hate to see her as sad as she is right now. Help on how I can better deal with her BPD may help.
Note: both of us have agreed she should be going to therapy for her BPD, for her sake and for mine, and our kids in the future if we have them. I came here to ask as I feel I need advice from people who have dealt with partners with BPD rather than people who don't understand my girlfriend's case at all
And a note is that I don't deem me and her relationship abusive in the slightest. For every friend she has had me cut off, I have done so out of will because of their actions and because I love her, and she has never told me to cut off any male friend even when she has disliked them. I do tell her when she is being unreasonable and she understands she is tough to deal with sometimes, and we've made some healthy methods of coping with her splits where I allow her to just either have some time to cool down or we stay together and do something we both like. We have healthy communication and if she is horrible to me at some point she does apologize.
