Boyfriend going away🙄

I’ve been with my boyfriend 6 months now which I know isn’t long however he’s a proper ‘lads’ lad and likes going out with his friends which is fine however he’s already going to Ibiza this year with all his friends and their girlfriends (I’m not invited) he’s going to a festival with the lads as well this yeah and now he’s just told me he’s going abroad for 3 WEEKS with his mates and their girlfriends and again I’m not invited. I don’t know if I’m over reacting and getting annoyed about it is immature of me. Of course I want him to go away and enjoy himself but I can’t help but feel a bit pushed aside. I just wanted other girls opinions would you girls be mad?!
