Op is he controlling? I find the fact most of your furniture he picked a little concerning, now he appears to be acting jealous of some non existent new boyfriend, when he’s the one shagging around, what are we at, 3 seperate affairs, with the same woman, that you know about, I’m sure you’re aware there have been countless others you don’t know about.
he also seems to think you will let him shag who ever, and as long as he tells you it’s over, when he decides it’s over, or more likely she did, you will willingly take him back,
it’s some of the oddest behaviour I’ve read about.
the biggest concern is the poor children living in this utter chaos, not knowing when he’s going, knowing about the other woman, and what that models of relationships to them from both of you, knowing he’s a rental,
it’s really cruel behaviour to them,
