What happens after a depressive episode?

I (M44) have been in a loving relationship for 9 months, with a woman (40) who informed me early on that she has BP1. Ours thus far has been a wonderful, loving and intimate relationship. We are at a stage where we both sought a long term relationship and we were working towards a long term future.

We have spent a lot of time together, many nights, trips, cooked together....the good stuff.

When she was "up", her term, she was quite spendy, sexual and effusive in her love and her happiness.

A few days ago, she descended into a depression, which reared its head in the form of insomnia for 3 days, then confusion, then a final spiral which sees her now in hospital.

Her family have taken to the hospital, where she is under supervision for one to two weeks. Her father has written me in text to not visit her. He explained to his daughter that I am bad for her, a bad influence, I kept her up. The opposite is the case, I would often dialogue with her about how she is feeling, I would call her out when I caught her stealing in a store. She has money, she couldn't resist the temptation. I would speak to her about her meds, ensured that she had doses at my house...etc.

The day before she ended up in hospital, she was a dark, paranoid version of herself. She had never been so angry, so nasty. Suggested that I am a bad influence. I had never heard this before. She had never said these things to me.

It was tough.

I received one message from her in hospital, and it seems to indicate that she now believes I am the reason she is in there in the first place. But she wants to talk when "she is better".

Has it been anyone's experience that their partner came out of this experience and were the person they had been in a different headspace? Or did their worst sentiments in the spiral become the new narrative?

How long does an episode last? I miss her, I want to hold her. Even just as a support.

I am in a purgatory....is this over? I will wait, I want to be there, I want to help and support her, want to help now. I have the tools to be there.

I am struggling, but focusing on trying to keep busy.

I don't want to text or call her, allowing her to focus on a clear mind, sleep, peace.

Has anyone come out of this with a clearer partner?

I know I asked a lot of questions. Any help would be much appreciated.
