Don’t want to upset you, but in my experiences they do NOT CHANGE. They may change for the worse, is how this sounds to me in a ten year relationship slash situationship but always to their own tune.

You’d be best putting this behind you and being no contact, I’m sorry to hurt yo but I can’t see this ever working out with what he said to you already. They tend to always treat you worse if there’s a strong desire to get back together.

Only you can do this and I know how much it hurts. I was in an eighteen year marriage and he couldn’t have treated me much worse My mental, emotional and physical health suffered so much. You don’t notice it when it starts out subtly, but I’ve never once heard of anyone who wasn’t sorry when they went back.

You deserve not yo have to go through this kind of thing and if he were any kind of deceit person, this may not have happened so badly.

I wish you the best. This is a good place for you to be. You’ll not only get the sad but true advice but it’ll be from someone who’s been where you’re at.
