Have you considered that it's ok, and very do- able to not be in a relationship? Reading what you say here, I don't know how you can come out of this without some new emotional scars. This shouldn't be what a relationship does for you. Shouldn't it be about enjoying life together? Seeing new places, laughing and having fun?
Why would you want to continue to spend time with someone who makes you feel so insecure and doesn't want to give you what you need? You're better off without it.
And, some people are cowards, they would rather hold onto a relationship that isn't good than be without. I don't know about you, but being kept on the hook for someone who doesn't even like me anymore sounds like a crap deal.
If he doesn't have the internal fortitude to end it, do it yourself, you don't have to get permission, or agreement, it isn't right for you.
