Am I overreacting. My bf invited a girl to his friends bachelor party.

So my bf is going to a bachelor party in a few weeks for a good friend of his. He’s in the military and the guy is in his squad. It sounds like all the guys that are going to the bachelor party are from this squad. There is also a female in the squad. Nothing wrong with that but my bf ended up calling her and kinda invited her. Now from my understanding the girl is a lesbian. But idk I can’t help wondering why he would invite her if the other guy whose bachelor party it is wanted her to be there. He would’ve invited her. When he called her he also said her name in like a sing song kinda way. Idk maybe I’m overthinking. Should I talk to him about it? I don’t want him to feel like I don’t trust him.
