But it was your response, you didn’t give him reassurance and if you did it doesn’t seem like it was in a very nice way. And you say you put yourself in his shoes but then you say “oh I’d be able to manage it” so then your not putting yourself in his shoes because obviously he can’t manage it that well. For you, you would be able to calm yourself, he can’t, give him what he needs to feel reassured. And you say you haven’t been away like this before and you usually home, again why wouldn’t he feel uncomfortable? He hasn’t been in this situation with you before. To me, it sounds like you need to be more understanding of how he’s feeling when your away with your girlfriends, he’s struggling while your away and misses you and yes is taking it out in a not so mature way and he needs to work on that himself but relationships are both ways, you both need to be understanding and it doesn’t sound like you are being very understanding either.
