he could be busy with family or sick or something just give him some time to breathe right now ur making urself sound a little clingy and thts not so great.... so just give him a little bit and he'll explain
No don't bother him sometimes hey don't like girls getting into there business wait at least 2 more days and then you have every right to call him you need to make sure he isn't cheating. 3 days is fine though
Nothing is wrong. one thing guys hate are obsessive girls, in a relationship there are different priorities which involves personal priorities. don't be like the other girls who cry just because he doesn't text you.
