My boyfriend recently asked me if we can try some kind of “open” non-exclusivity (which is somewhat common in the big city gay world). 

My gut says no, this is a terrible idea, but I’m trying to be open minded. 

The biggest immediate problem is that I’ve gotten really bad insomnia for a few weeks, mostly driven by how I get these surges of visuals of him being intimate with another guy, like some kind of visceral future flashback. When I experience that visualization, I feel very anxious and can feel strong abdominal tightness, all of which prevents me from sleeping.

I can’t resolve my relationship situation today or even this week. So in the meantime, how can I squash these unwanted intrusive visual thoughts that are keeping me up at night?
