My boyfriend broke up with me 2-3 weeks ago and now he sniffing my hair, hugging me a lot (when we were together he hated hugs) and he kisses my forehead bye when he leaves, now we still live together because we're still best friends we just wanted to see other people let's not get into that. But yeah, what's normal ex boyfriend behavior ? and why is he act like this.. It's strange right?
