What Can I Do?

I recently cut ties with my partner and it’s been a roller coaster. I will narrow this down to the specifics. The events listed below are in chronological order:

• caught SO talking to other people which they denied. I suffer from mental illness and explained in great detail that it’s already impossible for me to trust my own thoughts and that lying only furthers that problem and drives me to really dark places. Even when confronted with actual proof of them chatting to other people, they still denied and said it was the mental illness.

• cut ties. Broke it off and everything was fine. Last texts from SO read along the lines of “I love you…..I’m sorry I made you feel this way….i wish this would’ve worked”

• I message 2 of SO friends, telling them about some of the things that SO had done behind their back. (This was beyond petty and immature)

• SO goes to family member stating they feel unsafe and that I am a threat to their safety. There is about a 1-2 hour window in between our last conversation and this happening, directly after me talking to SO friends.

• I am told by other people that SO family member is going around to people in a program that literally has “anonymous” in the title. Stating false claims such as “checking me” and seeing me heavily intoxicated and drugged up at a recent party. None of which are true.

• I reach out to SO and ask what the hell is going on to which I am told they are getting a restraining order on me, no explanation

• I continue to spam SO asking why they were doing this and the massive negative impact it would have on my future. They respond by saying to stop contacting them and that they are calling the police.

• I continue messaging SO pleading for some sort of explanation.

Fast forward to today (this happened a few days ago)

• one of my friends messaged SO to vouch for me as I was (still am) beyond distraught and was contemplating taking my life due to the situation. And the last year has been beyond brutal for me, this was the cherry on top.

• SO replies by saying that they are no longer taking legal action. SO then states they wish they could be there for me during my hard times and that they want to see me get the help I need (which I totally agree with)

My question is, WTF just happened?!

Why wasn’t it until I contacted SO friends that the claims of feeling unsafe and threatened by me came up?

Why was my name thrown around to so many people in a program based on anonymity? Along with that, why did the family member spread false claims and rumors about me?

Why did SO go from restraining order and law enforcement to dropping everything and stating they wish they could be there to support me?

This has caused me unimaginable mental distress, to the point of contemplating ending my life. Along with my reputation being drug through the mud with false claims and rumors. AND, during the relationship, being purposefully lied to while knowing and witnessing the distress it causes me but continuing to do it anyway.

What can I do here legally? If anything. It feels wrong and unfair to let this whole situation go untouched. I genuinely suffered from this and will continue to for a very long time as my character and reputation mean everything due to the career I am pursuing. I also was inches away (quite literally) from taking my life due to this.

Any and all advice is appreciated.

(For anyone of those concerned, I have sought medical and psychiatric help from professionals)
