We've all been there and the moving on is a safeguard in itself for you...hardening you up a little...at some stage he has to make a definite choice as to whether he wants you permanently or not. You make the decision to move on, tough it out and he is forced to make a decision....
In the meantime you are distancing yourself from him and the hurting/craziness is lessoned...
Yes it takes a while and easily up to 6 months or way longer in some cases but what is the alternative??? You tell me...
