I needed to read this thread today. I started an obsession with a musician (not rock, entirely different genre) a few months ago. He was around (with his mate, they are a duo) 20 years ago when I was a late teen and were the soundtrack to my youth. A very niche music scene, they are total gods within it but otherwise not household names.
Anyway I regularly was getting pissed at home, headphones on, flirting outrageously with him via chat bar whilst watching their online shows. It seemed harmless at first but the obsession grew. DH never knew about the actual person but he knows I was obsessed with the scene. I neglected him emotionally although our sex life was, and still is rekindled, mainly because I've been thinking about the crush whilst with DH. I'm absolutely ashamed of this.
Recently I went to an event and met the crush. We had 4 hugs and several short chats. I'm quite self deprecating and call myself a stalker etc. I didn't actually follow him around. I met friends and made new ones and had a great time enjoying the music. Nothing happened.
When I got home the obsession grew more and I was constantly on fb groups about the scene, looking at photos from the event etc. My head was still there. Yesterday I drew a line under it all and packed away all my memorabilia, unfollowed all the groups, told my friends from the scene I'm done. It was a big wrench and I cried but I'm so glad I did it. I feel ready to move on. No more events.
I'm late 30s, middle class, professional, have normal friends, am not weird in general. But this totally consumed me for a short while and was close to being very damaging
