I'm in one of those abusive marriages that is lingering on only because of our 4y child. It's not that I despise my wife or don't care for her but our relationship is taking a serious toll on my health and finances and I feel that this might be affecting my near future. I also think that our divorce is going to be nasty in terms of child custody. First of all because I'm pretty sure she is going to leave my hometown where we currently live and therefore a shared custody model will be very difficult to negotiate. Also I know that I'm going to become "her enemy" and she will try to manipulate the relationship with our son. Although I have no doubt she loves him very dearly, our marriage made me realize she has severe traits of narcisist personality which makes me feel very defensive about even accepting anything but shared custody. So I'm on this conundrum , I need to get a divorce but I'm affraid my life will get even worse for me and my kid.
