My dating life question

May I ask how a symbol of commitment will stop the arguments?

What do you mean by compatible?

Do you have like interests? same education? same goals? same work ethics?

If sex were NOT in the picture, would you still stay together?

I think having a symbol of commitment would make me feel better about what we are doing and that we aren't going to break up, considering all our problems. However, common interests are some but we do disagree with a lot. Someone I feel like maybe I could be with someone better...

I don't really even like having sex with him, considering all the pain it's put me through.

A symbol of commitment isn't going to make any difference. Why are you staying with him if you're not happy? You want to spend the rest of your life with someone you don't get along with? It might not be this guy's fault that you don't get on but you're obviously not compatible. Say goodbye before you do have some kind of commitment ( like a ring or a baby) and go and meet someone you can be happy with - he's out there.
