Pick up ALL slack in parenting, and document it. Insist on a separation agreement that frames a temp custody order, and that is agreeable to you.
Unfortunately, this PP is right. She has surely been advised that she's going to get custody of your child even if she's the one cheating.
Get a very experienced lawyer who has represented fathers against mothers. (And I say this as a woman myself. You need a tough lawyer who will be aggressive with her lawyer.)
Document EVERYTHING, never do anything (like agree on who gets your child when) on a handshake, and whatever you do, find some way to ensure your child is never being driven by her if you suspect she drinks. That would be my No. 1 fear, that she would drive your child somewhere while drunk.
I'm so sorry. Fight hard for custody and like PP says, ensure that you are doing all parenting tasks and have evidence of that. But most of all, lawyer up NOW and don't say yes to anything "just between us, without bringing courts into it."
