Getting together after a divorce?

Alright, so my parents have been separated for two years now and divorced for six months, things are better considering there is a little less tension at home. My father no longer lives with us but is here nearly every day. Here recently my parents have been talking more and just now they were cuddling on the couch. Personally I do not think this is okay because my father is still VERY much in love with my mother, and my mother does not want anything to do with my father. I’m tired of her stringing him along, I’ve tried to talk to her about it but she doesn’t see eye-to-eye with me. Is it wrong of me to not want my parents to get back together?
