Hey man, I think your feelings are completely fair to have in this situation.

When I read this, I can understand how someone can arrive at that conclusion; Trying to build up an impression again. Finding things to connect over:

• he wanted to know about her favorite places there and some recommendations.
• talking about how he falls in love with her favorite place there and how he can't wait to get back home so they can talk about it when they meet

So, its okay to feel uneasy about a lot this. Same thoughts would run through my head.

The issue thing is... we don't know if that is the reality.

That is just a theory.

And until we know what's factual, you're going to need more information.

You can be open with your partner and express how you feel. She could provide you with reassurance, and there is a chance she might even see your side too.

I know for myself, I have no desire to maintain an ex friendship because I know the potential metal battle that comes with it. I don't want to force my GF to deal with that mental load. Your GF might see it that way too, who knows.

But anyways... until you have more evidence. You have to stand by this:

>I'm at peace with that fact because I trust my GF and I know she wouldn't cheat on me.

Trust your GF until she gives you a reason not to.

And if you discover that he's making romantic advances, and she doesn't put space as a result... you have your first reason to explore your suspicions.
