ExH and I have been divorced for 4 months. ExH has 2 DC from previous relationship aged 5 and 8. We were married for 3 years. We also have a 1 year old. DC and I now live in our own flat and have done for the past 8 months. Coparenting with our DC is sometimes challenging but generally smooth sailing.
Recently, he has been bringing his 2 DC with him whenever he drops off DC back to me. He tries to instigate conversation, random suggestions that we should all go out as a family one day. This makes me uncomfortable as I don't have feelings like that towards ExH anymore.
My issue is that I'm not comfortable going on days out with his 2 DC. I loved them while we were together and I still love them now.
But I have a separate family now that it's just me and DC in our own space again.
AIBU to not want to have much to do with ExH and his DC? Or am I being cruel?
