This is one of the biggest differences between my current relationship and previous LTR.
Do you always know where they are, and if not do they tell you? E.g would it bother you if they had stopped off to see friend/family on their way back from work and then came home and never mentioned it and you only found out when the friend/family member mentioned it to you in passing?
No, he's always doing stuff like this. Going out to do one thing but coming back after doing two or three other things, often not mentioning it until later. Now I too do the same.
This would never have happened with the ex, we were always in touch with each other during the day, talking at the end of the day about what we'd done and who we'd seen.
Do you know what they spend their money on and how much they spend and do you ever ask if you see them with something new?
Nope, not a clue. Totally separate finances. If one of us had something like a new jumper or new book, we'd probably show an interest though.
The ex and I had a joint account (as well as separate) so a lot of purchases were joint decisions.
Do you have individual savings or shared?
Completely individual. Every now and then we say how really we should write down all of the accounts in case something happens to the other, but we don't get around to it. DP in particular is like a squirrel with lots of accounts collected over the years. It'd be a nightmare to sort his estate out.
Do they share private information relating to their friends and family
We both confide about our families, especially if something is worrying us, but I keep stuff from him about friends that they wouldn't want him to know. I've just asked him and he said his friends don't really have those kinds of deep conversations in the first place.
