My LTR admitted to hanging out with her ex-FWB in the last few months (guy she hooked up with before me). She says she hates the guy, but because they are a part of the same social circle, they sometimes hang out in groups. This all came out because she was going on a road trip with her friends, including this FWB.

Is it unreasonable for me to feel this is disrespectful to me? Am I being butthurt or too insecure about her remaining in contact with an ex in group settings? I understand she isn’t seeing him one on one (he lives across the country), but I still feel hanging out with him in any setting isn’t respectful. Part of me feels like I’m a hypocrite - I am still friendly with most of my exes, but I know from experience, they are never just friends.

I failed to establish a clear boundary. Is it too late to do so?
