Hi Confuzzled104
I agree with you, being jealous is not only about the fear she may cheating.
What about dig a bit deeper about your fears?
for some reason I felt jealous, anxiety like she was having more fun without me.
So its perhaps about your own self worthiness. Feeling not interesting, funny, ... . you name it, enough.
For me being jealous has a lot to do with comparing. And i think its a difficult topic, so
for you to face it.
