Please try to remember our counsel to be patient and really watch your mouth (and fingers when texting/emailing). You can be impatient and your impulsiveness causes you to react in a trigger-hair fashion thus causing you two more difficulties than necessary. One such example was posting on the FB. There are many more ....but I don't want to list them here.
Instead what I want to do is to re-focus your attention on finding a way to calm down your racing thoughts and emotions before you approach your W. There will be many, many triggers that crop up as you travel the road toward piecing. The trouble is, the way I see it here, that you have NOT YET mastered in how to manage them effectively.
By being reactive without thoughtful contemplation, you are contributing to the to-fro tension between you and W. What can you do to change this dynamic? You are THE ONLY person who can control....yourself. Not W. W is entitled to confide whomever she chooses to do so about the M difficulties. This the one-eyed control monster rearing its ugly head right there. Try to be more self-aware of this tendency of yours, buddy.
Yeah, I am with CBT....cool your jets and bring those concerns to a MC who will be able to facilitate communications between you and W in a neutral fashion. It is clear that emotions are running high between the two of you as you try to figure out the next steps in healing from the A.
Slow down. Breath. Go for a walk. Contemplation is your friend...seriously. Contemplate and reflect before opening up your mouth. For what you put out there cannot be taken back.
