do i have the right to be annoyed?

iv really liked this boy since december, and i found out that he likes me too (since dec too)
and now iv found out that he got off with some girl on a french trip while i was relli relli relli missing him....
im sooo upset, but we arent going out so do i have a right to be annoyed with him? just pisses me off that while i was missing him he was doing that
the exchange was in jan btw

and how should i act tomorrow? should i confront?

What ? You have the right to be annoyed about whatever you want to be.

I can't believe everyone is saying you don't. Tomorrow if you are annoyed then let him know. Something as simple as "I know we aren't together but I thought you cared about me enough to not do this". Unless you're the type of girl that's going to stick around anyway.

You don't have the right to expect him to care or expect him to do anything about it though.

I tend to have a erm ... lets say stricter moral code then some of my friends do and I get annoyed at them when they do certain things but I don't expect them to care. I can get annoyed about whatever I want.

I got really annoyed at Coleen Rooney and Abbey Clancey recently. For letting their husbands get away with sleeping with prostitutes while they were pregnant. Great thing for Rooney's son to grow up learning is OK. Crouch's daughter will also grow up thinking you should forgive husbands for doing it. See I have no right by many definitions to say anything about that but I do it anyway. Society annoys me sometimes and I let myself be heard when it does even if I "don't have the right".

I'm surprised I haven't got more neg for it on TSR
