I see that people are still referring to you living with them, not as it actually is. They are living in your apartment that is attached to YOUR house.
My understanding is that they don't have to interact if they don't want to. If you would like to talk to your former-in-laws and let them know that you don't want them to feel obligated to rent from you then fine. But I really don't think you should toss them out as long as everything is good between you. I think you have already discussed boundaries and as long as everything is laid out I think it is fine. Hopefully that includes not talking about ex.
Yes I think you are still hung up on your ex. It takes a while and if I have learned anything is that you will be ready to let it go when you are. You certainly will feel less pain once you do but no one can say it is time get over it, because it is different for everyone.
