Bluesummer, don't let it bother you one bit..
I was once like that.. until college started.. then there was no more time for any Mr.Social..
So..
If he's the type of guy who listens to you, cares about you, and you can honestly call him a sweetheart and a careing soul... then.. chances are that he's only trying to be helpful.. Guys like this feel useless in life, and need to make themselves into a valuable resource for others.. Try to remember if he went out of his way to get you to go out with him, if his gifts were ever really thoughtful??? This is that type of guy then Blue... For as long as you let him know that he really means alot to you and that you adore all the things and attention he gives you and does for you.. then there's nothing these other girls have on him...
However.. if he's your regular low self-image type of guy, who wants all the attention he can get.. then first of all.. let him go... lol.. you seem like too nice of a girl to be with someone like this... This type of guy is usually not responsive, fake-caring.. not helpful.. STARTS agruments often... questions your loyalty to him... and.. is very VERY practical... If you've ever gotten jewlery after jewlery after jewlery.. or anything like flowers, chocolates, teddybears... OVER AND OVER AND OVER again... he's PRACTICAL... doesn't want to bother thinking too much, maybe not even at all.. so he either stereotypical girly gifts.. Does he compromise to do things YOU like??? if the answer is no.. then.. be afraid of his PRACTICAL nature...
When his "Friend(s)" need company or a shoulder to cry on.. he might just cash in on the chance to do something with them.. I know plenty of people like this...
But don't let me scare you.. I just want you to have a good idea as to where you stand.. hopefully your guy will fall deep into one of the two that i've just mentioned.. since the other types of guys tend to be quite the opposite of a Mr.Social...
