My ex messaged yesterday to let me know he is dating someone. It shouldn't have come as a surprise, but it did. It shouldn't have upset me so much, but I was devastated. I haven't stopped crying. We were married 17 years and only separated in January. It was a mutual split and I know the relationship wasn't fixable, but we were actually getting on better than ever this summer and the whole time he was on sites actively seeking someone else. Dating is the furthest thing from my mind and I have been completely focused on my children. I feel stupid and angry but mostly sad. I don't know how I am going to even be able to look at him let alone be friendly. I am hoping someone else appreciates what I am going through.
