What has happened two months ago? Just like any addiction, a porn addiction is a coping mechanism to deal with mental health issues, a tragedy, infidelity, grief, lost of a job, low self esteem, insecurity, avoidance because of a physical or health issue, involve the with someone on the internet or work, etc. The only thing that’s going to work is communication. Have to tell him how you feel, ask him why, what happened, what is his thinking of this, etc. Maybe he just wants out of the relationship. If he doesn’t cooperate, pack yer stuff up and leave. It ain’t worth it.
