Eldest DC has gone to his dad's for the first time since we split. I will probably get flamed for this but I feel so low, DS really likes her. I am happy that he's happy don't get me wrong but it's just reopening the only slightly healed wounds from the last year. For context it was an affair, she was the OW, STBXH left for her officially I suppose when she fell pregnant. It's just been me and my baby DC today and I feel like I could barely function. I think I'm just coming off the back of parenting solo whilst they enjoyed their fun and holidays and lives while I held everything together and now I'm finding it hard to let go. Any words of wisdom appreciated. I feel like I should be grateful he finally after a year wants to parent but why do I feel so shit about it.
