Welcome to the board. Have you read Divorce Remedy? It sounds like, from what you have said, that your relationship with your exh will take a while to build up again. Nothing is impossible.
Divorce Busting teaches that there are stages to reconciliation.
You haven't described that there are negative feelings between the two of you. Would you say you were in the friendship stage?
My advice to you is to lower your expectations at the moment from reconciliation to friendship. Work on being your own woman, having a full life and being friends with your exh. He will see how fabulous your are and increases your chances of being an attractive prosepct again. After all there is something very attractive about someone who is independent and fun and something unattractive about someone who is needy and from whom you feel pressure. It is also a lot of pressure to put on someone to get back together when you haven't been that close for a while and there is a lot of history.
Work on taking that pressure off him and being that fabulous you. The rest, if it is to happen, will come. And if it doesn't happen then you will be ok because you will have created a wonderful life for yourself.
Some of the things I did to GAL 'Get a life' a divorce busting technique was to - go out with friends and create fun opportunities - joined a choir and got interested in music again - spent more time with family - planned new and exciting activities - like I did a fencing course.
Not only was it fun, it helped me take my mind off my ex gave me, meant I had something to fall back on if things didn't work out with exh, and gave me new stuff to talk about that wasn't focused on our relationship. Quite honestly, it was the best thing I ever did.
