Probably he just shy, whats big deal about it? If this problem can cause u break up den in the future there is more simple thing can cause u to break up with other ppl, except that he deny to be ur bf when ppl found it out.

Every1 got their to busy with, except that he ignore u whenever u try to ask her out or just wan to have a little talk. U should give hom some space as well as giving urself too, find something good to learn and dun think of he can spent time with u whenever u need him.
