lol.
I was over this long ago, not soon after my last post on here i met a great girl and had a short fling with her which reframed alot of things in my mind.
Alot of reframing before doing anything with that girl also helped me realise a few things in that relationship with the ex-fiance.
Basically i was holding on not to her or the feeling of love, but to the idea of having someone. I guess that mainly stemmed from lack of self-esteem and self-respect. Also a doubt that i could get another girl who at the time i thought was quite wonderful. Reality is quite the contrary. Changing myself and hiding my desires shouldn't have been a requirement to having a relationship with her.
The thing that really helped was taking time off to find ME again. Discovering what my needs and wants were, what I desired and what makes me happy 
Now i am dating a few girls and things are going pretty good. Flashback memories from time to time but they aren't bad 
Advice i would give to anyone thinking of getting over their ex would be to focus on things from a 3rd person perspective and to realise that a relationship with anyone isn't about filling part of you, but adding onto what you already have.
