If he has already moved on then it would be pretty difficult but if you feel like he's starting to drift away from you because you are too possessive then give him some space and see how he reacts.
SOMEONE that truly loves you...wants to be with you and spend time with you.
To him, you are his everything.
Does he say he needs space or are you feeling that you need to give him space?
If he says it , then he may be feeling cornered.
If you think it, maybe you need some space from him...
Just a thought....
depends on the guy and the present relationship.... if its a new relationship... space usually means break up..
Depends, if he's just asking for the odd day off now and then it sounds reasonable, but if he's planning on joining the Foreign Legion then I would start worrying.
