Girls trip?! Plus 3 guys?

So my best Friend and I planned a girls trip and it was supposed to be just us girls but she ended up inviting 3 guys that we all know and are super cool with but my boyfriend doesn't really know the guys well.. So I talked to him About it today and he told me to go and have a good time and he won't Be upset as long as my pussy ain't loose when I come home lol. Then he started asking all these Questions as tho he was not for sure if I should go. I am stuck in the middle as to go or not to go. I just don't want to disrespect my boyfriend or any of that nature.. But I also want to go and have a good time. People are telling me not to go but he seems cool with it I'm just confused.. What would you guys do?! Would you go or would you stay back ?!
