Most Helpful Girl
he could very well want to break up, but, I actually had this same thing happen with my current boyfriend. we've been together for a year. at about the 2 or 3 month mark, he kinda distanced himself/acted cold for like a week. after a few days of it I did what you did - I left him alone and waited for him to contact me and he did after 3 or 4 days acting totally lovey and into me. we're still together.
i think some guys distance themselves when they want to break up, but other guys do it when they really like you and have the freakout moment of "oh sh*t it's getting serious - I need to make sure she isn't clingy". by giving him his space and not contacting him, you'll show him that you're not a crazy-clingy girl, which is what he is afraid of. if you let him come to you, you may end up like me, in a happy and healthy relationship a year later. after that little distance he became way MORE affectionate and loving, and I think it;s because it was the moment he finally realized he wanted to get serious with me.
like I said, maybe he wants to break up. but maybe he's like my boyfriend and is just testing the waters before becoming more serious with you.
