UPDATE.
Well... the mid 20s guy that moved in with me for a month left already. We had a great time together, going out, hanging out, weekend day trips, etc. I got used to him being around. And sexually we were a great match. Almost everyday I woke up fucking him, or him giving me a blow job, or just kissing. I love to kiss and he enjoyed it to. We had a lot of sex. It was great. He'll be living very close by, like 5 min away, so we hope to still see each other and he might stay over when he has days off. I'll be back to living by myself and going into my usual routine that I also missed. So everything turned out great!
As I mentioned before, ex-Escort did not moved in with me at the end, he's going to AA and he is now in good terms with his family, his new job is going well, making 2x more money than in the past. I'm glad that I was a safety net for him, in case he couldn't make things work with his family. He felt safe with me having a place to go to. And still I told him, I'll be here for him when he needs me.
Thanks again for all your feedback and input! Everything turned out great at the end!
