I'm sorry to hear about the situation. That's very difficult. The reality is that the court will look at your past, including your alcohol abuse and any history of violence, when making determinations as to child custody
. However, if it can be shown that all of that is well in the past and that you no longer behave that way, the court may decline to give that much weight. The court will also consider the way your wife treats the children and the effect of that on them, and that consideration would include any emotional abuse. The court looks at everything relevant to make a custody decision, and that includes all of those things on both side of the matter. It's not possible to predict the outcome, but it sounds like there are things that way for and against you, so you would present all of that to your attorney and he would try to show the court that the child's best interests are served by placement with you, were you to seek a divorce. With alimony, the court likewise considers a variety of relevant factors, analyzing the age and health of each spouse, earning abilities, financial resources, needs, and ability to pay. The matter is discretionary for the court and the determination is made based on the consideration of all of those factors.
Please remember that my job here is to provide accurate information about the law. Providing bad news is the hardest part of doing my job but it's a big part of doing my job well. If you feel that the law is wrong or unfair, I'd strongly encourage you to contact your legislators, as they are the only ones who can change it.
