Something also to think about is how your children will fit into this. It's definitely positive that you're able to co - parent in a healthy way. They will notice this and learn from this.
I'd caution, though, too much physical affection or a lot of time spent at home together with your children, just because that can get very confusing for them, especially if things are up in the air for you. Saying from experience, from having children and having to explain the breakup with a partner and why he's no longer at home, make certain that whatever time spent and traditions made now are ones that you can foresee being able to maintain in the future, whichever outcome materialises.
