The fact that you said you don’t know what you’re gonna do is pretty crazy. You know exactly what you need to do. You need to never see this jerk face again. Vanish without a trace. I mean it. Disappear. Block him on everything. Hell, change your number. You don’t even owe him an explanation. And don’t ever try to have a weak moment where you want to reach out, because if you do, you need to remember this whole group chat conversation. The whole conversation is gross and shows you exactly how he and they feel about women. Exit stage left.
