Future, if you can have some of that "family" time and not have it mess too much with your head, its really great. Its great for the kids and really probably good for you both in the long run--but again, if you can do it without it messing with your head. A friendship could lead to something between you in the future, or, at the very least, a friendship is better than an "enemyship" where the mom of your kids is concerned. Hope you can do it without it setting you back. If you find that it does set you back, its time to pull out those boundaries again!
