I have a sister and half-brother who have not talked to me since our mother died 6yrs ago. I say life is to short to be so petty. There is a saying stab me once shame on you stab me twice shame on me, NEVER again. And guess what life does go on. I have made peace one to many times and now it is their turn. I don't want to sound negative but keep your guard up. Hoping all turns out well for you and your family.
