My boyfriend had asked me if he could go to a party with his friends a week ago 
So I told him yes that there was no problem thinking that he probably wouldn't take that as a actual yes 
I thought maybe he would instead stay over at my house that night 
It wasn't a club or anything if those parties it was actually a wedding 
But what really bothered me is that he didn't invite me to go with him instead he said he wanted it to be a boys night out 
So not letting him know I was mad 
He actually went to the wedding yesterday 
Without me 
I feel upset because in our relationship he doesn't like me going to any type of party with my girlfriends 
I feel so many types of ways right now
I need advice is it ok to be mad !??? 😢😤😩😔
