When my partner was 41 he started dating a 28 year old woman. They were together for 4 years and engaged. She got him into BDSM as he had not done this before. She told him if he really loved her he would do BDSM. He went along with it but said he didn't enjoy it. He was the dominant. She was quite abusive to him in the relationship with constant put downs, shouting and ended up cheating on him. After they split he was so low he contemplated taking his own life and had his notes ready but a friend realised what was going on and saved him. After he went to counselling and rebuilt his life.
Recently we were joking around and he pulled me in for a kiss, after he said he still had the dominant side left in him. He later said jokingly what did I think when he said about him having dominance in him. I got really upset and said I'm worried he will want to find someone more adventurous. He was horrified and said he loves me and does not want anyone else. He asked how long had I felt like this. He said we when we go on our adventures he finds that adventurous. He said he does not want to do BDSM as it ruined him. He said he no longer has any of the equipment.
Is it possible he can avoid revisiting BDSM altogether? It seems unhealthy his ex told him if he loved her would do it. I'm not criticising anyone who does this, it's just not for me. I just don't want him to possibly relapse when he has the opportunity to leave me now. He has not asked me to do anything like this or attempted it.
