Enormous and unstructured rant alert. No need to reply, am just filled with a need to get it all written down so it isn't in my head any more.
My ex walked out on me and the 3 dcs a year ago - had been having an affair for several years with a family friend (began when my youngest was 5 months old), and is now living with her. I am proud of how far we've come - I navigated the divorce, am putting my finances to rights through hard work and parsimony, we've established a contact pattern for the dcs that they are comfortable with, and we have an uneasy truce. He desperately wants to be friends and for me to admit it was the right thing for all of us (!!) and I can just about bear to have a conversation with him without being rude. I've lost weight, and have a pretty good social life - my friends have been great and really rallied around.
But my goodness I am miserable. I don't have the same crushing despair I had at the start. I am over the anger (although I would not necessarily be able to restrain myself if I ran into the OW). I can see there is lots to be grateful for - we are all healthy, we are fine financially and I have lots of support.
So why do I feel so bleak? I look at my dcs, who I love so much, and see children whose lives have been turned upside down and who are never going to know the security and happiness that I had as a child and that they deserve. I wonder where I went wrong every day - I know that it was his decision, not mine, but if I'd been thinner, less distracted, more focused on trying to keep the marriage exciting, perhaps it would have been different. I don't particularly want him back - I can see all of his many flaws - but that doesn't mean I am happy about the fact that he appears to be having the time of his life (we live in a small-ish town, as do they, so plenty of people are happy to update me).
I also feel sick at the thought that they will at some point start a family of their own. I think that will destroy my dcs. They are more or less accustomed to the idea that their father doesn't live with them any more, but how are they going to come to terms with the idea that he now has a new child who he has chosen to live with. dd1 has already been in tears at the idea more than once (apparently he told her he was looking forward to having more children. He is such a tosser...)
I cannot begin to imagine ever meeting anyone else, and I can't really see where I would find the time or the energy. I don't really want another long term relationship but it would be nice to have some male company and the occasional date. I feel like I'm holding it together on the surface but am just so fed up with being responsible for all the decisions, and all the hard bits of parenting. He gets to dip in and out, and do the good stuff, then has the cheek to tell me when he dropped them off this evening that we "should both be really proud of them, as they are great children and we've done a great job".
