I would definately talk to a lawyer about using this info to ensure you have sole custody of your daughter. He should not be allowed unsupervised access to her. He clearly has some serious problems.
Actually, knowing all this about him....if you do allow him to have access you might be changed with child endangerment! So, keep everything documented carefully with dates and times, see a lawyer, and stay clear of that controlling sick man.
You are doing a really good thing getting help with this issue early on! You are going to be a strong mom for your little girl. Good luck!
