"The most expensive thing in th world is TRUST, it takes years to earn and just a matter of seconds to lose"
.. try not to let them creep in..convince yourself now that it was just a quickie.. no emotion.. no cuddles.. nothing of any quality.. he just used her and went back to work.
..try to minimize their time together if you can..
it can do you no good to obsesse about all the crap that didn't happen.. if that's any help to you..
focus on you and your health
Did they make out in our family car? What kind of sex, how long, and it only gets more graphic. Same as you asked, did she fellate him then kiss me? For a solid week I drove myself crazy with this.
I do try to reason it like somanyyears suggests and it works better as strong emotions simmer down.
After only 2 months for me it's better, though.
I'd recommend that even if you try to work out your marriage in some ways you emotionally disconnect from him and these activities. I've had to do it to keep myself sane. In some ways it makes my WS upset and makes her feel she's losing me, which she is.
It sucks so hard but it is normal.
