Custody of the kids?

Hello again. It's been such a long time since my last post. I'm sure you're wondering if my life has improved since my last post, and the answer is No/Yes. Let me explain. The Ape I have a legal contract with better known as my spouse is still an A-Hole. He's still verbally and emotionally abusive, and sadly I felt Its impacted my relationship with our kids. The positive is my way of thinking has somewhat changed. I have completely snapped out of the "we're supposed to be married, and he's supposed to love, respect, honor, and cherish me" way of thinking. Hell, last night he snuck out claiming to go to Walmart at 1AM  and came in at 7AM acting like he was outside watering the lawn. And truth be known. I didn't care. Karma's a bitch and he seems to always get what he deserves in small but obviously spells of Karma. From, car accidents to traffic tickets, to twisting his ankle or injuring his back. Somehow the evil he sends my way always boomerangs right back at him. I don't even have to pray that God punish him anymore it just happens. Anyway, my beautiful kids that are feeling the brunt of my frustration, anger,  humiliation, and stress. It's so so sad what they see everyday. It's so so sad, how they rarely see me happy. And they act out which makes the ordeal even worse. Let me ask you this. Would you give up custody of your children because 1. You despise their father 2. Their lack of respect for you is a reflection of their father's influence 3. Lack of funds 4. And  overwhelming frustration and anxiety. Would you give your bastard spouse custody knowing he may not be the most suitable parent to truly care for them? What would you do?
