Seems a bit thoughtless, My girlfriends brothers and sisters came back from University and their work abroad for the holidays, she and I did have plans but I asked her if she still wanted to meet up or have time with her family... She picked her family, which is OK with me since I know it'll have been ages since she seen them especially since they live a good bit away! So I'd understand the family bit, but usually I put my girlfriend ahead of my friends... I don't follow that whole bros before ho's crap, especially since I'd not even consider referring my girlfriend to the latter... But I mean, good friends would understand that your girlfriend would want to see you at Christmas surely? I mean my best friends all did... I think it's the draw of friends and fun he's after, I'd not say he doesn't like you but he might be a tiny bit selfish, no?
