My partner of 5 years doesn’t live with me. This was because we both had under 18 kids. Our oldest kids are now 18. So in theory neither of us live in single adult household. My partner has his mum in his bubble as she is lonely.
We followed the rules last time. But our relationship will not develop if we can’t meet-up indoors this time. In theory I assume we shouldn’t visit each other’s home. In theory.
