Had a big fight with 2 year LTR that ended with her threatening to pour water over me with a water bottle, I took that bottle from her and poured it out on her myself (I normally dont react much to this type of stuff but I was just trying to sleep). She went to her parents, originally intended to only be for 1-2 days. Ended up showing up announced at our place to pack her stuff and leave, and from the way she texts it seems like they are doing some kind of legal action against me (she avoids answering my texts, but didnt block me, I'm thinking a lawyer told her to do this)

Now rationally I know there's no coming back from this. I am in full fight mode rn, trying to get the money she still owes me for this months rent and gym membership. I already decided a couple weeks ago that while I enjoy my time with her, her mental issues are a dealbreaker for having children and eventually I would need to break up with her anyway. Overall (before the recent events) she's very loyal, puts up with a lot of my bs, still horny for me after 2 yrs, a good girl except the frequent fights from her mental issues that started in the past couple months. I made her go to therapy 4 months ago and have been trying to get her on psychiatric medication but she refused so far, and at this point I tried what I could to fix her. Part of me thinks this is a very good thing to happen to me.

Help me stay reasonable like this. I am already starting to rationalize reasons to get back with her when she inevitably comes back. To be fair to her, she likely only left me because she was afraid I will might her out (she's always extremely paranoid I will leave her). She is also easy to pressure by her parents, you wouldn't believe the amount of stupid shit she's done before just after 1 phone call with them, it always leaves her unhappy and telling me she regrets doing it. There is a high likelihood they are making her do this, I know with any normal woman it would be crazy to think this but I believe it.

Attempt to answer own Q: Obvious, dont contact her and lawyer up if needed
