Does it mean he's thinking to break up with me?
oh. i remember giving that advice to a guy friend who confided and told me that he wanted to break up the girl for some reasons.
i told him to re assess the whole situation for a period of time (preferably a week), no communication whatsoever (not even a text message) but use that time wisely. since his reason was not because of another girl, i told him not to check out new available girls around.
it's not fair for the girlfriend who loves him so much.
thus, ask for that space, and re assess the whole situation. in the process, it may give him the light as to whether break up or probably work things out.
