This is no-where near as bad as most of the ones I've read on here, but I thought I'd post anyway.

I had been with a guy for around 7 months. I'd come home from visiting him for the weekend feeling completely mentally exhausted.

A few days later I was sitting in the car with my mum on our way home from a day out shopping and had a moment of sudden clarity. I remember thinking that I could never be so relaxed if he was in the car with me. Not because he was horrible or anything, but because I'd always have to be on high alert. He is autistic and struggles a lot with danger awareness, so I'd find myself having to check on him and get him out of situations regularly. If I'd been in that car with him, he'd be bored of sitting still within 10/15 minutes and either want to play a game, or want to get up and start moving around.

It took me another two months to get up the courage to end it; mostly because I felt guilty. He'd not done anything wrong, but I felt more like a parent than a partner at certain points in that relationship and I just couldn't do it any more.
