I am a woman and my dBPDh begged me to have kids, it was a fantasy that they would fill that hole inside of him.
I think thats exactly right, they use children to fill that hole inside them, but it never works. Same goes for pets, my BPDexgf keeps getting pets hoping to fill the void but then neglects them
It took many years, fertility treatments (donor sperm, thank god) and finally had 2 babies. Of course while I was pregnant he started using drugs and by the time they were 2.5, he added in strippers and hookers. Yeah, having children with a BPD is a nightmare. He wasn't using drugs or cheating until after I was trapped with small children.
I am very grateful I dodged that bullet. Although I would like to have kids one day, it would need to be in a mature, stable r/s
