Newbie here. Help

We’ve been together 6 months. Dating 6, together officially for 3. Thought I had found “the one”.

First argument tonight. Blew my mind. Cried my eyes out in a way I haven’t done for years.

Could you guys kindly explain what the hell I’ve just got into and if there’s any hope?

She’s had therapy for decades, seems very self aware (one of the things I felt was really healthy between us), but tonight was just…flabbergasting.

She woke up ill this morning and said she’s been struggling to mentalise recently but I don’t know if I’m / she’s / both making excuses.

I think it’s time I try to understand as much as I can:

• I don’t want to stay in a relationship that could fuck my life up (fun fact: I’m recovering from a neurological injury and all the trauma that came with that as is)

• I don’t want to give up on a relationship that maybe could be fixed because I started reading Reddit forums on it and panicking (granted - I can see how could be justified)

I am also aware that my own circumstances may be clouding my judgement - in the sense I am quite isolated and spend 90% of my time alone (solopreneur and live alone in a studio flat).

Meeting her felt a bit like home. Fuck.
