I've been with my DH for 8 years, married for nearly 2, childfree by choice. He's my best friend, so kind and considerate always and we have a lot of shared interests which we enjoy together. We split housework 50/50 mostly, and when we don't (he does marathons so sometimes cooking etc. falls more to me when he's doing intense training) he acknowledges and appreciates my extra effort and I'll get flowers and dinners out to thank me. Basically it's a very happy marriage and I would be devastated if we split up.
He doesn't give any indication that he's any less happy than I am, except for this one thing. We're moving house and going from a very expensive city to a much cheaper location, so we are very fortunate to be releasing some equity. We keep our finances quite separate, we have a joint account for bills and the mortgage but otherwise we keep our own money. This has always suited us fine. He's always been a higher earner than me and pays significantly more into the joint account. He's also very generous in treating me to things as he knows I have a lot less to spend. He paid most of the deposit for the home that we are selling. Because of all this, I suggested that we shouldn't split the equity equal ways as he's contributed more and he agreed - we are going to divide it into three chunks, one joint which will be the biggest pot, and then two individual pots for each of us - about a 60:40 split. I have no problem with any of this. We aren't talking loads of money here, it'll be less than 20k in total after stamp duty and other fees.
What I DO have a problem with is that he wants everything we've agreed in writing. I don't understand why. I've asked and he says he just thinks it's sensible. I tried to make a joke and said something like 'oh are you planning ahead for the divorce?' and he just laughed it off. He sent me an email draft of our agreement and it's so formal. It hurts to feel like that he doesn't trust my word on something like this, and that he's potentially thinking ahead to how we divide assets if we split. I don't know if I am overreacting or if this seems odd to other people as well?
