Is it wrong to be bothered by watching my fiancé interact with people who are into her?

I’ve been with my fiancé for 6 years and for the majority of that time, she has been great at making me feel like I’m the only guy in the world. (We live in extremely crowded area) <br><br>Lately, I’ve been noticing her interacting with others in a way that’s different than how she has for most of our relationship. She flirts a little with shopkeepers and some men we meet in social situations. She’ll go out of her way to try to make guys smile and laugh, and she’ll obviously return their flirting. She’s gone on lunch dates with a couple of coworkers. She seems to generally be enjoying talking to men more lately and, to be honest, it’s bothering me a lot. <br><br>I’ve tried talking to her about it and she insists that there’s nothing wrong with being friendly and that she’s not doing anything that would make me look bad or embarrass me. <br><br>But I can tell by the way other guys look at her and talk to her that they are into her. And I don’t want to be in a relationship where my partner is flirting with other people. <br><br>Is it wrong if I put my foot down about this? Or am I an a\$\$hole for not being okay with her being friendly to others?
