Have had good and bad relationships. But the previous 6/7 years I spent single were great. Really have me a focus of what I wanted, what I was willing to compromise on,(not a lot honestly).
Really got to know me. When I did meet someone I was able to put firm boundaries in place.
We don't live together, we go for coffee a few times a fortnight, and I stay one weekend a month.

The rest of the time is my time. I don't want to share my home again. Or have to consider someone else every time I do something, I already have four kids I do that for.

For me, and him that's enough. Maybe it will last, maybe it won't. Either way I enjoy being single more than being in a full time relationship.

Maybe it's just getting older and realising life is short enough to do what you want without putting things on hold for the sake of a relationship.

Ideally of course we wouldn't have too.
Ideally all relationships would accept each individuals motivations and ambitions. Unfortunately it rarely works out that way.

Anyway good for you OP, take your time to grieve, don't try and tell yourself you shouldn't just cos he was an ***.
The loss of a relationship still requires healing. So be kind to yourself and take it slow.
Try doing something YOU wanted to do for yourself once or twice a week.
And don't let your thoughts runaway with you, once the relief has passed you might find yourself second guessing yourself.
Keep this post and remember how it felt the day after.
Take care. Namaste.
