I’ve not been in a similar situation as to your history, but I do have experience with reconnecting with an ex for one reason or another, even if only a one-time deal.

To piggy-back on anita, I might consider laying out the focus of discussion too. If it’s just about your daughter, make that clear at the beginning and stay firm in keeping to that conversation. Personally, I would absolutely stay away from any topics that might boil the blood (your relationships, his, other family or close ties, illness, whatever). Saying you’d rather not discuss those things, for now, is going to go over better than discussing them when there are still strong negative connotations with those topics. Resentment and negative feelings are the last thing you want to come into play, so keeping it casual and light (as you can, depending on the situation with your daughter) is the best bet.

As I read in another forum post on here, the fear of falling is worse than the fall itself. Outside of the potentially serious daughter discussion, my best advice is to try to Keep it Light.

Keep in mind why you agreed to meet in the first place. Good luck, this is a tough one, especially when you’re not sure what to expect.
