So my boyfriend friend is having a Bachelor party they’re flying out to Miami

He was never invited but they recently told him if he wants to go to tag along and i don’t want to be controlling but I kinda feel uncomfortable with him going his friends are my friends so I know how the boys get ( such dogs ) and it gets me annoyed that he said I’ll see if I have the funds and go without asking to see how I felt about it ??? LOL I wouldn’t fly out anywhere plan trips without seeing how my partner felt about it lol? Am I right ?🤔😳
