Less AIBU, as I'm pretty sure I am, and more 'how can I stop being silly about this?'
We are very lucky to have 3 beautiful DC. There is a large age gap between number 2 and 3 because DH wasn't sure if he wanted any more. He eventually decided he was happy to have another, but was always clear that would be it. I was/ am on board with this as I do think we're at our limit now, and would struggle for a myriad of practical reasons to manage any more kids. Plus I'm really rubbish at being pregnant, and found it much harder with DS3 than with the older two, being that much older myself.
Anyway, DS3 is now 15 months and DH has finally got round to booking a vasectomy and I am struggling SO much with the idea, which has taken me by surprise a bit. I know it wouldn't be sensible to decide to have another child, but I find the idea that there would be no possibility at all of a happy accident for some reason very hard to live with. I'm also still only mid-30s and most of my uni friends/ similar aged work colleagues are only just starting to have kids so feel it's quite early to be definitively done.
DH has said he won't go ahead if I'm not ok with the idea, but honestly I don't think I'll ever be 'ok' with it beyond where I am now - which is agreeing for practical reasons that 3DC is probably enough, and feeling strongly that it's his body and his choice, so I shouldn't really have a say. I hope once it's done I'll just accept it and be fine, but at the moment it's really upsetting me and I'm struggling to have a sensible conversation with him about it.
So AIBU? (Yes) And therefore any tips on how to get over myself?
