You know they say that time heals. All I can say is that you have to allow yourself time to feel hurt...because its okay
Three years is a LONG time to be in a relationship and just call it quits. Prayer is an excellent outlet for you to tell God how you feel, why you feel, and whatever else is on your heart. But remeber that you also have to come to a point where you are ready to listen and be able to hear what HE says. Remeber its two way communication. But it sounds like you are on the right track. It will be okay because weeping man endureth for a night but JOY cometh in the morning. You have sisters here who you can vent to when you need it.
