I told him that he has until the end of this year (the end of our contractual obligations for work) to find a job and get himself into a position where he can take care of himself and move out. He has not begun that process.
If this is what you want, to divorce or at least start with a legal separation, then it would be best to create a back-up plan.
I was in a very similar situation as yours, from the soliciting sex, to laying on the couch, and not taking any action to get a job. I wrote about what you are writing about 4 years ago on this site, and nothing seemed to go as I wanted it when it came to the logistics of ending the relationship (we lived together for 4 years, in my house, with his son from a previous marriage).
I gave him a timeframe about getting a job and moving out. I was trying to wait till the end of the school year, so it wouldn't disrupt his son. That was the plan. It didn't go that way, and got messy in the end.
First, from the moment I told him that's what I wanted, he started to leave the house with me to care for his son while he went out partying and carousing. That ate away at me. Even though I knew the r/s had to end, I still felt I loved him, and to see him go off with other women while he was living with me was heartbreaking.
Second, he never got a job. It was all he could do to hang on, and use it for me to not kick him out. He either didn't think I was serious or felt he could play the victim card and I would succumb - which I'd done so many times before.
It came down to me escalating the time for him to move out, and doing it even though he hadn't gotten a job yet. It was my mental stability vs. trying to be nice. I opted for my mental stability. He took his son to his friends house and lived there. He had options. Not the best ones, but he wasn't living on the street.
What would you do if he didn't have a job by December?
The complicated aspect of all of this is that we have 3 children and the law is not on my side. If I chose to move forward with a divorce, it'll be difficult to prove that he has a personality disorder if he is unwilling to accept responsibility and that can make it ugly and messy for the kids.
I know I'll have to share custody and I'm not sure that he'll be able to provide a warm, caring, nurturing, safe environment for them and that's not what I want for them.
I would suggest that you start a thread about this aspect on our Family Law board. The members there can suggest steps for you to take so that you are doing the most you can regarding custody. There are things you may be able to do to strengthen your case. You can access that board here, and start a new topic:

I hear you, and respect that you recognize by staying in such a relationship it can have a detrimental effect on your children, in addition to being a dissatisfying way to live your life.
