I am a fairly new poster, but read here freq.Unwanted divorce 15 yrs ago. Ex left me for OW that he still lives with, but apparently no marriage plans. I was very devestated concerning divorce and it took me years to really recover. Reason I am here, Since divorce 2 of our 4 children have had some 'Issues" and my ex and I have had to have contact on a fairly regular basis to help them. Our oldest son was diagnosed with a mental illness approx 4 yrs ago, so in order to help him, we have had a lot of contact. We both belong to a parent support group, and are the only divorced couple there. His OW has no interest in this, and does not attend any functions. My problem is this--ex seems to think we are like good friends , sits by me at the meetings, laughs and jokes around, etc. Unless you knew ahead of time, you would not know we were a divorced couple at these meetings!!My problem is this continued contact and him acting like everything is fine, andeveryone is over the divorce, is playing havoc with me, It has stirred up feelings of caring that will get me nowhere. I need his help with son, and I can't leave support group as I am on the board this year. I still care very deeply for my ex. Divorce didn't stop the love. HOw do I handle this and protect my heart?
