Hi bct06001-
Your girlfriend is dealing with some serious emotional baggage right now concerning the deterioration of her family.
By PUSHING the relationship with her, you are actually reducing your chances of reconciliation in the future. Do not force the issue...simply accept her decision and allow her the freedom to heal on her own terms. The more you PUSH the more damage you are causing down the road.
There isn't a predetermined measure of time that you can put your finger on regarding the healing process. Typically, a 30-day window should be an appropriate amount of time. Everyone is different though...keep this mind.
I would suggest to eliminate contact with her during this time. If she has not contacted you once this time has elapsed, then give her a call but only as a supportive friend.
By the way, you can't make her be with you and there is no secret formula that will change this aspect either.
Who knows, she may contact you before this time is up.
Please keep us posted on your progress.
