I don't know the situation with your loved ones so I can't really give any advice on if or how it possibly could be fixed. I would say that in general it is best to try to go the extra mile before moving on...if not for hope of repairing the relationship...at least so both parties have a clear understanding of each other's feeling thoughts and reasons for there to be less feelings of confusion anger mistrust etc. Because leaving a relationship with residual raw emotions can be very damaging to one or both parties. The pain of loss is inevitable...you must take your time to grieve. When you're ready to start moving on you'll know..don't jump the gun just to not be lonely. It may seem easier in the present but can greatly complicate the future. Just some thoughts. I don't know if any of this applies to you...but I hope it helps.
