I've been dating this girl during the summer, and then she broke up with me for someone else. 

I was still deeply in love with her, which means that I care about her, so we're still talking on a regular basis, and we've maintained a good friendship (with highs and lows of course)

Anyway let's start:

- Wednesday: a friend of mine wants to make me meet a "cute and funny" friend of his. I'm not in the mood to meet new people, but the conversation becomes funny so I decide to post it in my instagram stories. My friend wBPD has unfollowed my profile time ago, but she still watches my stories sometimes (which is weird because that means she manually searches my profile in order to see the stories). Anyway she sees that conversation and all of a sudden she becomes JEALOUS AF. I mean why?? You're in a relationship. Anyway she starts asking questions, and in the mid afternoon i reply saying it was boring. Jealousy turns into happiness. It was a while since I've seen her so happy, sharing things and being extremely talkative. In the evening all of a sudden she stops replying.

- Thursday: she messages me first stating things like "I adore you" "You're super funny" and other validating messages. Then we talk for a while. She is sick, at home, so I ask her how she is feeling daily.
She says the results of the Covid swab were out in the morning and she's negative. Her doctor prescribed her antibiotics. I warn her to end with the antibiotics not when she feels better, but when the prescription ends (because I know her well enough, and I don't want her to develop resistant bacteria). She gets mad and starts venting that she's taking the pill though. Then she stops replying.

- Friday: the morning opens up with her threatening suicide. I've been able to calm her down, and listen to her. I put some boundaries because I didn't want to validate her behavior (and enhance reinforcement learning), but at the same time I didn't want to devalue her trigger, so I listened to her and we tried to find a solution together. Once she's calm she starts venting about her BF "it's interesting that you care more than he does", "Now I'm fighting with him". After a while again, she disappears.

I was worried because this was the first time I've seen her suicidal.

- Saturday: I ask her how she is doing today, she says it's better than yesterday, but she is way less talkative and is acting defensively. She says she has solved the conflict with her BF. Silence treatment (and I don't get why, I literally just asked her how she was feeling).

- Sunday: she apologizes for not answering yesterday. But I'm super busy for the whole day, so I'll reply to her tomorrow

- Monday. Silence treatment all day. But she is stalking my insta profile.

- Tuesday: short conversation, but she is not responsive so I'm not insisting.






So, that's it. She's never behaved like this (except for the silence treatment, I've received a lot of it).

I was extremely worried when she threatened suicide because she lives alone, it was the first I heard it, and she threatened it multiple times in a couple of hours. I didn't want to show her how much I was worried, so I tried to be as calm as possible.

She's an amazing person, and I do care about her a lot. I want her to feel good and loved, not only when she's at her best.

So I'm trying to understand what's happening, and if you have any advice on how to behave I'll appreciate it a lot. 

I know she's dragged me into the push pull as with weekly patterns she's pushing me away/pulling me. But this week was different, she changed her mood on a daily basis.

Also, I've already told her how much I care about her, so I'm pretty sure that she knows.
