I have been feeling that way as well, angry, sad.. I want to scream and cry at my H and let it out. Anger is tough to check and have slipt a couple times. I do best to check it when H is around and not so much when alone,
When you mentioned your W and plans, that they dig deep in the pain. I know what you mean. You may be feeling ok and then --Bam-- the plans are a constant reminder where they are not. My H tells me has plans w/ work ppl and knowing colleague he has feelings for involved is tough. It is taking his time and energy away and painful. As mentioned this is a good place to vent and get support.
