wow, us number people are so rare in RL! I wonder if I can forge a research paper and publication outa this 
[not really] but it is very interesting. I can remember loooong strings of numbers, have always got some kinda maths happening in my head- for no real reason... thought it was mild OCD of some description
jynier- wow to learning the haka!!! I once visited the polynesian cultural centre in hawaii, was brilliant. I have a lot of relatives in NZ who I have never met (my father's family were from there originally)
midwife agreed LTB will be the response. maybe for a reason. but you need time to process that yourself. I can act like your DH does, when I am feeling low/depressed/down/out whatever. I can go months without replying to emails or texts and things and completely neglect all relationships. It doesn't mean I don't want that relationship, just that I am not in the right place myself for it.
If it is the case, then I can see how if you love him and have a good history, how this could really hurt you. But he won't really be able to process that, until he snaps out of it one day and realises, by which point it could be too late and he could have lost you.
OR the cynical, yeah, he just wants the comfort of the marriage, none of the real stuff, and wants to protect himself financially.
I think May is reasonable, that's a few months away. Heartwrenching in the meantime but imagine you will feel such relief/clarity once you have reached a conclusion.
camwombat thank you for eccles link! (have clearly led a sheltered life)
