seperated 4 months, its now 9 months, oh and om

[help67]

So as my coach said, she thought I should tell my ww how much she hurt me when she told me about om last week, and that I believe and trust in her to do what is right. My coach thinks we should continue to build on the friendship we have built these last few months, she thinks it is also best for my d. I should also tell her how this was a wake up call for me, and that these changes are for me and my d regardless of the outcome for us. I mistakenly told her the changes were for me months ago, I have made many mistakes.
I dont know how long she is with om, if it is a pa of just ea. The sitch is crazy, om is in open marriage, my ww, om, d all take a tkd class together. They all hang with a group of friends and do other things together. I think my w feels accepted for who she is, but I feel she is being used, I know I made her feel that way too.
I guess I can start like this, and if I cant do it, I can then let her know at that point. I wish om was just a random guy, but they were friends first. Om is in open marriage, he is using my w, and I dont know if she cares or what, he fulfilks her deep emotional connection she wanted from me.
