I’ve started being able to recognise when I split on my partner. He wants me to always be totally honest with him, but I feel that if I told him that I’ve split on him his feelings will get really hurt because he’s looked up BPD and knows what happens during splitting. 

Is it best to try and communicate with him that I’ve split? I don’t want him to think I don’t love him but when I split on him he is bad in my mind even though rationally I know he’s not. I don’t want him to know the bad thoughts I have when I can’t help them. 

What should I do? Has anyone else had this issue?
