Glad to hear that you are piecing your life together. Unless you really don't want it, I would count my blessings in having your ex-H wanting to be friends. Personally, I think staying in contact helps in the healing process. You have a long history and children that will tie you together forever. I don't think we ever really get over or forget the other person. We just move on. I think that forgiveness of the other person, and of ourselves (yes, we have to forgive ourselves too), is the most important aspect in the healing and closure of a M that failed. Once that happens and we are able to become friends (maybe friends is too strong of a word) with our ex, then I think true liberation occurs in our lives.

Accepting friendship is as simple as staying in touch.

Sorry to hear about your broken heart, but time will heal it.
