XP and I split up a year ago, it was a joint decision, nobody else involved and we have been amicable ever since. We have a 3 yo DD who lives with me, he sees her regularly and a mutually agreed amount of child support. I am quite happy on my own with my little girl and am not looking to start a new relationship anytime soon. So today he tells me he has been seeing somebody else for 'quite a while' and has in fact been living with her for the last 6 months. He wanted to discuss when and how to introduce her to DD which was fine and we agreed that he should take it slowly.
I'm not really sure why but I feel a bit sad about this. AIBU to feel sad that he has moved on? I guess it was inevitable that one of us would meet somebody new and it has been a year now but we were together for almost 10 years and it just seems so quick to me. It's so easy for men (or NRP of either sex I suppose) isn't it? He has DD one evening a week and one day at the weekend so other than that his life is his own whereas my life revolves around work, DD and keeping up with everything around the house.
Feeling a bit sorry for myself
