Since splitting with my ex, 2 out of my 3 best friends have stayed friends with her (same sex relationship and my friends in question are all female).
At the latter part of my 14 year relationship my now ex was violent towards me on a few different occasions. Since the breakup, my ex has caused me a lot or problems and just been generally difficult and plain nasty at times. All of the above my friends are aware of. Both of the friends I'm mentioning are friends I introduced to my ex and my ex has a huge circle of friends all with children the same age as our son. My ex used to see her circle of friends all the time but since our breakup 2 years ago I've heard of only a few meet ups with her circle of friends yet my two friends she sees with our son consistently (one of them every weekend and every day of those weekends).
AIBU or stupid to be upset over this? I feel really hurt that my friends know what my ex has put me through but yet they continue to see her, one of which is even closer to my ex than she is me now and we were like sisters before 😞
