LeaJ, I saw your thread yesterday, but didn't hve time to read it.
First of all, I hope you have a means of support, be it independent income, a job, welfare, whatever, so you won't have to depend on financial support from this man. If you do accept any kind of support from him, I would suspect he will feel entitled to his share of time with your child. I agree that any evidence of his perversions will help in negating him from yours and your daughter's lives. That really is your strongest suit against him. If you have such evidence, he may also be reluctant to have it surface in public, considering his job, etc.
I had just posted a thread here in the Relationships forums yesterday about recurring memories I'm having of bad past relationships...all the way back into my college days. I'm 62. Regarding this, in your present situation, and for future reference, it might be a good idea for you to take stock in why and how you became involved with this person and the current entrapment in which you now find yourself. Learn from it, and grow to be a stronger woman and mother, not allowing yourself to be further entrapped by this man ...or any other. I was in a 20 year marriage in which my husband threatened to take our daughter each time I tried to discuss divorce (from the time she was age 2!). I hope for yours and your daughter's sake, you find contentment and freedom!
