I have a friend relationship with my ex. I got there by internally forgiving her for the infidelities she had committed and recognized that since we have two kids together that we were going to be connected through them for quite some time and it would be easiest on everyone (most importantly our daughters) if we put the hurt and pain in the past. So my relationship with her has morphed into somewhat of a brother/sister type thing. We get together once a week on Sunday, which is the visitation transfer time and all have dinner together. We alternate at whose house this is going to be at. If she needs help on something I help her out and she does the same for me. I look at her in a totally different light now and it seems positive for all of us, especially our girls.
