Should separated (but not "legally" separated) couples date or wait until divorce is final?

I am divorcing my wife who has a mental disorder where she si a serial cheater and liar. She has 10 years of therapy ahead of her, she has Borderline Personality Disorder and almost a year of therapy under her belt. We have two children. She is not advised by her therapist to date and to work on herself first. I too would like to be celibate until the divorce is final as i want to completely finish one thing before starting another. I see no reason to bring in third parties until our divorce is final. They could complicate and create friction that is an already tenuous process of filing bankruptcy and then filing and finalizing the divorce. Again, we have kids involved and a lot to do. It is highly-advised to file bankruptcy jointly no matter how much a couple cannot stand each other. We are mostly civil. And i am aware that since she has been a serial cheater and serial liar due to her disorder that she is prone to fail if we agree to being celibate and single until divorce and joint matters are totally severed. She says her therapy has her stable enough to honor this understanding to the end. I have my doubts, but I am in no hurry to get into any relationship until way after divorce is final. The children will be a lifelong shared products of the marriage and we both are fully aware of that needless to say.
