WAS wanting to move across the world - help

[whywhy]

So, there was a nice video chat with the kids this morning and she kept asking me how I am. She also looked really down, but I didn't say anything about that, just said I'm good and kept it short.

I had to sign the kids up for something that needed her approval (I want all financial decisions to be joint). It was quite late there, but I messaged her and asked to talk. She kept avoiding talking and just kept messaging with odd comments like "do what you think best, I trust you", etc.
I felt something odd, so facetimed - she answered from a bar at like 1am there.
She then called me back a few minutes later to tell me that she was out with 2 girlfriends.
I just said that I was sorry I bothered her and next time just to text me she's out and we can speak the following day.

Why is it bothering me so much??????????? I'm not saying anything to her, but it bugs the hell out of me.
I know she can do what she wants and we did make an agreement that we would stay monogamous, but I do think there's an EA developing.
I'm here with 3 kids and she's in partytown!
