Hi Memphis
Are there others who keep their relationships outside of the home? How does it work for you? The other person? Can it work? I don't ever want someone I love to feel like they are limited in their ability to be in my life (not sure that made sense)... I don't want someone to feel excluded, I suppose.
I can understand why it's daunting and a little overwhelming for you to be getting back into the dating pool, especially from this new angle.
I think that there are plenty of people who live apart and plenty who actually prefer it this way
For instance, whilst my partner lives with both myself and her husband in the same house, she has a third partner who does not live with us. They've been together for about 18 months, are in love, and consider themselves to be in a potentially lifelong non-'primary' relationship. He has never met our daughter and we don't generally introduce other partners to her or talk about them with her. This is because we worry about her getting attached and hurt if we broke up with that person. At some point, she might be introduced to other partners - she knows that we are poly, but she's only six and we're trying to keep it simple. I have no issue with people approaching this differently - this is just how we approach it right now.
As for me, I actually often prefer some degree of separate living, even with a 'primary' partner. I love the fact that my partner already has a husband, because I get some time to myself. She shares a bedroom with him and sleeps in my room about twice a week. This is ideal for me and I don't feel any less important because of it. My ideal is actually to have my own studio/ADU attached to the main house so that I have my own space.
In terms of additional partners, I am actively NOT seeking another live-in situation! So, it is perfectly possible that you will have a future meaningful relationship with someone who doesn't actually want or need to be a bigger part of your life in the conventional sense, but who is very happy to just enjoy time and love with you in whatever format is feasible.
Edit - Another thing I meant to add is that one of the beautiful benefits of poly is that we can sometimes find ourselves in relationships with people we wouldn't choose as live-in partners, and therefore might eventually break up with if we were monogamous. Being poly offers us the opportunity to have successful live-in relationships whilst enjoying other kinds of relationships if we wish to.
