Hi NotreDame,

he is very appropriate with the children (he is an educator). He has a mild form of BPD and educated himself on the illness and works on himself regularly... .meditation, exercise, self improvement books, socializing, therapy, stopped drinking alcohol knowing where his mood leads to if he does.
Id like to welcome you to bpdfamily. I’m sorry that your dad and kids are going through this. If you check th discussions around the board your dad is doing work on himself the disorder does not define him as a person, i look at it the same way as coparenting my kids mom is undiagnosed and certainly not doing the work but the r/s is between them and my ex uBPDw, the same goes for your H is the kids r/s with your dad. Your H has to find a way assuage his anxiety.
