It could mean so many things.. in any of the ways immaturity is a key factor. The others here are right too you can't make him change and he may or may not grow out of it but one of the possibility is that he could be cheating.. i have experienced the "hanging with friends" excuse and later found out it was a girl or even girls with him and his friends.. now, i'm not saying he is cheating but just don't make excuses for him in your head.. friends should be part of our lives but our partners should be shown respect above all else. And i did ask the G@Y question so many times too! But why have se x with men when you can do it with willing women?? ahh so you asked what would i do.. well, i would tell him how i feel about what he's doing and give him simple and easy to follow solutions that are non-threatening and if it is really bothering you and he doesn't stop i might get out of the relationship if i were you. If it's not going to get better it's going to get worse.. put yourself first and someone else will put you first too.
is it that he's always ditiching you for them or is it because he just enjoys a boys night out? strech your week out and tell me how many days he spends his time with you, and how many days dose he spend time with his boys? if it truly dose seem like he cares more about his friends than you, i go and ask if i'm allowed to go and hang with his gang!! go and chill with the guys, maybe it's a sign your bf wants you to get to know them! chill with them, and once you've spent some group time, tell your bf you don't mind them, but you also want some alone quality time with him! - his answer will determine how mature he actually is!!
hope this helps :)
Tell him how you feel about it. Don't just stand by and let him care about them more than you. One upside is he cares about his friends. The down side is he cares more about them than you. Also and indication that there might be a problem in your relationship. Just talk to him and see how it goes.
Best of Luck
Find a guy who cares about you and his friends, incorporating the two, but understanding the limitations and needs of the one. A real man knows that he needs to spend time nurturing his relationship with his significant other, and can make her feel secure enough that he can go out with his friends without her.
I think it's an indicator of immaturity, and you can't force him to grow up...that only happens in it's own time. You can talk to him, but that usually ends up falling on deaf ears, if hanging with his friends is what he wants to do.
You might just have to live with it, till he grows up a tad.
I would tell him he is the most special person in my life and I would like him to feel the same way. You also have to make sure you show him how important he is, by doing simple sweet things. That way he not only hears it, he sees that you really do feel that way.
I tend to be on the skeptical side, so forgive me for asking exactly how do you know he cares more about his friends than you? What behaviors exactly get to you?
he has a bird that looks like you and cares more for his mates :S have you asked him if hes g@y?
