Well here's my experience thus far:
My H has admitted to me he has an addictive personality. He smoked and drank. He loved to gamble and admitted to me he would leave enough money under his car mat to cover airport parking in case he went crazy in Vegas.
So he curbed his own gambling issue. He is not really into computers so he never hooked on online gambling to the best of my knowledge. He has had some sex issues but I did my best to accommodate them to keep it 'real'. My main thing with porn on computer was all the freakin computer viruses. So WE got some DVDs. Man that stuff is not made for women. I would sit there and feel myself splitting between date rape victim, cultural expectation, disgust and psych major observer! Totally not a turn on for me. But I tried bc I'm a Codie ha ha! He is 11 mo sober on the alcoholism. Did it via inpatient rehab and some AA and some Spirituality. I've been wondering what is next, but maybe it appears smoking is solo for now.
And sex now? He claims he feels neutered - nothing. I am coming up on 14 mo no sex. I finally looked at those seedy posting on CL just this weekend. Gross. I'd be better off just propositioning one of the professionals at work - I could just ride the elevator until someone said yes. I could then drag him off the elevator for coffee to confirm his name matches his ID, get his cell number, and compare schedules to set up a "meeting". It is funny I am making a lot of gains in my recovery that could all be blown to heck over lack of intimacy.
Wish you well and keep your eyes open!
