You are very young. 31 isnt too late to still have everything you want. I think you are right to get rid of everything including the ex. It will be very hard to get over him if you still have contact. I had a boyfriend stab me in the back when I thought we were going to be married, I said all the things I wanted to say, all the things you can never take back. You need to tell him how you feel for closure, then walk away and dont look back. Everything good is ahead of you.
