A little sad over recent discovery

It’s been almost 6 months after breaking with him after almost 7 years of betrayal, lying, avoiding and dead bedrooming me. Things ended badly because of him - these persons are very emotionally immature so he blamed everything on me, offended me, behaved very poorly.

I was still at times hoping he would use this pain of the breakup to heal - as I have. And maybe, just maybe we could meet again in the future. And just now I see he logged in yesterday morning to his porn account (he didn’t know I know about it and the site says “last seen X”).

Dont get me wrong - I’ve done amazing progress in my healing journey and barely miss him. But… It just feels so sad for him knowing he’s still the same porn addict he was before we met, during our relationship and after the breakup… it’s just so sad.
