@Kristyn2022,
Question:Why did you agree to go there (where he and is ex got married) in the first place. What expectations would you have of having a good time? Where’s his consideration?
When he suggested it, your answer should have been a firm NO.
As for his flirting with others, that’s a whole other kettle of fish. An engagement after these sort of dynamics? Nahhh! That’s not going to end well. Limits need to be stated clearly.
Whether or not he’s over his expire isn’t so much the question. It’s Whether or not he’s over himself. that needs answering.
