I know AAK. The OP factor messes with the head and its so hard to sep out if you care about them (spouse) or just derailed because of feeling insulted by the situation, the "other" factor. In your case it seems like you are dealing with distracting other people (bandaids?), but the ever present other "relationship" is the affair your H. seems to be having with celebrity high life.
Regardless, its pretty horrible and astounding to be devalued-which is what this whole process does.
My H. also likes to toss out the "we are spending lots of time together, its not like I'm sleeping with her. It has nothing to do with what happened between us". Whatever, I no longer dignify this conversation topic. But it does remind me how self absorbed, out to lunch he is.
Hang in there today.
