Being with you and having your moral support might make it easier for him to comply with the terms of his parole. I understand what you are saying.

Being in prison can be especially hard for sex offenders. They have to be segregated from other inmates who are not in the same category. If that is not enough incentive for him, then it sounds like he doesn't mind that much, if he has to go back.

Some sex offenders get housed in psych units, where conditions can be somewhat softer than elsewhere, and they may find a level of relative comfort there. Again, I'm just saying that he may not consider doing the rest of his time "inside" all that bad an option.

He was so unmotivated that he couldn't even resist running to your computer to google up some porn. Are you really willing to live with that? He has already been counseled to stay away from porn. He gets by without it in jail. He wants to come home to you because that is where he thinks he will be most comfortable. But what about your comfort? You should be made miserable, so that he can be where he will have the coziest arrangement? You married him. You did not adopt him.

He doesn't want you, as a wife. He wants you, as a parent. You've had to take care of yourself for the past 5 years. Time he learned to do the same. He's telling you that, if you won't take care of him, then he would prefer to have the prison take care of him, rather than have to take care of himself. Then let him make that choice for himself. Going back to prison may end up being what kind of works for him. He wouldn't be the first convict to lean in that direction. Among his fellow inmates in protective custody, he may have a little circle of friends among whom he is not all that unhappy. (As a sex offender, he has access to some level of protective custody. And he gets special psych support.) I seriously doubt he is out there "walking the line" with the gang members.

I hear that you don't want to stay with him. You don't have to. And you don't have to get pulled into an argument with him. Write him a letter saying that you have gotten used to being on your own these past 5 years and that you would like to stay that way. Don't bother telling him that you don't believe in his innocence anymore, which you don't. Just say that you are pursuing a legal separation and that your mind is made up. You do not have to convince him that you need to do this.

The letter is a good idea. You do not need to go pouring out "all your thoughts and feelings." Of course, he will turn it all around on you, whether you say it, or write it. Just say what you think will be easiest for him to hear. Say you wish him well and hope he does okay, but that you have decided that you don't want to live with him. End of story. Don't ask for his blessing on your decision. You'll never get it. He will never agree with your decision to leave. He doesn't have to. Make your own decision by yourself, like you've been doing about lots of things for these past 5 years.

I would never tell any woman to leave a marriage that she wanted to be in, regardless of what crime her husband committed. I'm just telling you to do what you really want to do. Otherwise, you will hurt you more than you'll help him. Sometimes, you have to disappoint someone else, to have the space you need for you. See a lawyer to talk about your options, even if you have not decided yet, for sure. PM me anytime, if you want. You have been extremely generous to this man for years. Time for you to have a life that you want.
