Am willing to be told im unreasonable....partner has 2 teenage children who live with his ex. They live at the other side of the country. Going to visit means that to make it worthwhile he will go for a week or two. Thing is...he stays at the old family home, and that's with his ex who has " moved on" he says but they seem firm friends. So the whole time is just like they'd never split..family outings etc. Would this make anybody jealous? suspicious? If I tell people that this is how it works they go " oh yeah..." kind of really sarcastically, so they're obviously on that wavelength too..
