What should I do?

well, if im you, i'd rather look for another one..one thing about boastful guys.....they usually are kiss and tell.....im not generalizing but then, the tendency of boastful guys will be to tell all their prizes, awards (including their girlfriends) to their friends...and even not so close friends......but then if you really like him.....well, its your choice...

PEACH!!! girl, who is this guy? You aren't talking about him, huh? I've been through this also in the past and one important thing I've learned from this experience is to NEVER ASSUME OF ANYTHING. Yes, it would make you feel good and giddy thinking if he indeed likes you, but think long term, 'what if' he does not and only thinks of you as a friend? Guard your heart and try very well to not be overwhelmed with this guy's behavior. Unless you muster the courage to ask him direct to the point just so to answer your inquiries. Otherwise, you will just hurt yourself if in time it was revealed to you that he cannot reciprocate those feelings you have for him. Think about it.

if i were in your case..i wouldn't have hopes on it..though you have to optimistic about things in life, sometimes expecting the worse could give you the best joy ever..^_^ but i think that you should be friends with him..enjoy the time you spend together and cherish the moments that you know will never happen in a million years..i hope you stay happy as you seem..^_^
