بسم الله الرحمن الرحیم   

In regards to forgetting our past life memories when we’ll be reached in paradise (God willing), almost, I can remember a same issue as a related matter with your inquiry, that it was said that people will forget their past practices and lives when they’ll go to the paradise. (Of course it seems to be related to negative practices of the life, not good positives practices). Although it could be possible to remember our nice previous matters and events or whatever we are interested in.

Meanwhile, on the other hand, it could be considered as a rational issue that people will be free from bad memories of the world in order to be happy in the paradise and enjoying it. Otherwise it would be considered as a painful paradise! And God knows best
