I am a woman with BPD and I would say the quiet subtype.

Is it a common coping method to look for hookups without not caring much about who the person is? Just a quick way to have sex.

Also in a relationship have you ever found yourself feeling super empty and that combined with a state of low empathy made you commit infidelity? 

I don't want to trigger anyone but I feel like it is important to be able to talk about sensitive stuff like this.
