Sorry new here but wanted to get more of a female perspective if that's okay (appreciate there are plenty of men on here, so your opinion is also welcome 
).
Myself and my ex split up quite a while ago (we have two kids). Have been pretty much housemates for years (no physical contact of any kind since 2018) but then Covid hit and we found ourselves trapped (neither could afford to move out). We made it official a few months ago (when lockdown ended) and our house has sold but not yet completed, so we are still living together and will be for the next 2 months or so (hopefully less).
My ex has started dating, and has said she doesn't have an issue if I do too. I signed up to a dating site but couldn't decide if it would be better to wait until I was in my own place or not and kept pausing and unpausing my account. During one of the unpaused times I was contacted by someone and we've chatted by text and she wants to meet.
My current situation hasn't really come up in general conversation, so I don't know if I should mention it before we meet, during the meet or afterwards if there is something there and we get on. How big a problem would people find it? I've asked a few friends (mostly male) and some have said it's not a big deal and to just be honest before meeting but most have said to see how it goes first. One sighed and said I should have waited and it was bad.
I feel I should be honest and say something before meeting but what does anyone else think? Major problem or not really an issue given the last year?
