He said he will not forgive me and its unfair for me

Hi, I'm married, and stumbled upon an online game. I feel like there is something is missing in our marriage or my husband was always busy and away that's why I tried looking for games to pass my time. I found this interactive game where you can marry other players and have heirs. I started in January this year. In this game, you can find a player to troth and you can divorce them too. So I had 3 failed troths already. I cant help but be immersed in this game and get attached to my troths. Long story short, I have found a friend in this game who I always talk to and share things with about my failed troths. I found out that he fell for me and I told him I have feelings for him too and soon after I asked him to become my troth. Everything was going well and happy until he suddenly went MIA for 2 weeks without saying anything to me. I waited for him to go online every day. Each day was unbearable because I feel like he abandoned me but I kept waiting. I tried chatting with other players to pass my time while I wait for him. I asked them about daily things, stuff about the game and how Im missing my troth so much and Im waiting for him to come back. After 2 weeks  my troth went online, I was so happy but it was short lived because after a day, some malicious person sent DM to my troth telling him that I was chatting with players, telling them I am lonely and alone, forcing them to troth me and telling them that I miss them so much and all sorts of other lies. I told my troth its true I chatted with other players to pass my time while I wait for him, but I never told them I miss them and forcing them to troth me. Everyone in the servers we played with knows how I love my troth and that I am waiting for him always. Anyway, sadly my troth didn't believe me and wants to end things with me. I love this person so much, since January until now he was my support person, my best friend and confidant. We have shared so many moments together but with my 1 mistake of entertaining other players by chatting with them, everything is just falling apart. I tried begging him not to leave and break up with me. he said he loves me but the pain keeps haunting him and he just wants it to stop. I know this isnt the real world, its just a game but I already invested time and feelings. I know I should focus on my real life but I dont know how to move on from this.
