My ex gf and I had our relationship for 5 years with 3 years on off cohabitation for 2-3 months. In those 3 years we had 7-8 session MDMA/ketamine together in a naked 1:1 settings when we shared a lot of thoughts, future plan, deepest secret fears and desires. We have recently broke up but it seems so hard for both of us to move on. She's having a rebound relationship but still expressed love to me (???). I'm trying to move on with another woman but it feels so hollow. Is it very hard to move on because of the intense moments you share in those session as other relationship feels empty and not that deep?
