I just wanted to share my story even though it isn't really positive.
My ex gf was very jealous of exes and anyone of the opposite gender who I maintained a friendship with. I couldn't really breathe in that relationship, yet she was allowed to do whatever she wanted. Eventually she left me for someone else. I know this isn't a common outcome of a relationship with someone who is jealous, but it was certainly an interesting twist. I felt guilty for my friendships that she didn't approve of, but now I realize I shouldn't have felt bad. Those people are still in my life, and where is my ex?
I would consider compromising with my current partner if insecurities were to pop up, but I don't think I'd ever cut off a friend if our friendship was strictly platonic yet my partner was super jealous and insecure about it. I would gladly show my lover our conversations and stuff to make her feel better, but not excessively and not if there isn't any progress with her insecurities getting better. I feel insecure too just like the next person, but I would never expect my partner to end a friendship because it made me feel weird. I'd rather inject myself into the friendship and get to know the person so I could possibly feel better. If it were still inappropriate in my eyes, I'd call my partner out on it and communicate how I feel.
