I met my husband online. When we dated, I didn't tell my ex anything other than I was going on a date. It wasn't until I was serious about my husband that I said anything to my ex husband about who my new boyfriend was and what he was like. At one point, I let them meet when my ex came to pick up my son. At that point I felt that he deserved to meet the guy who was spending so much time with his son. At the same time my ex was dating someone new and that is when I met her because she was spending a lot of time with my son. Fast forward to now. My ex and I are both married to the people we are dating and we all get along great. Sometimes we even hang out, especially if my son has a school event that we are celebrating.

Hopefully something like this will happen for you.
