So I email an ex, we agree to meet up for a drink to catch up. I tell the current LTR what I am going to do and she doesn't quite flip her shit but definitely decides I've done something wrong. She tells me she see's the ex as a massive threat.

Doesn't tell me she is going to stop me but does tell me she is quite upset.

I hold my ground and say I'm just seeing her as a friend because she was my friend before I met current LTR and you will not dictate who I can and cannot speak to.

She doesn't fight but still is very sad and tells me she can't stop thinking about the what if's.

So the question is how does this reflect on me? Is the fact that she has a massive problem dealing with this a sign that I'm not treating her right (TRP style) in the first place?
