Is OTHER wrong in the post ? POST : I appoligize in advance for the formatting and grammar. (I'm on mobile)

  BUT am I the asshole for not wanting to leave my wife despite me not really being happy? Getting a divorce would absolutely destroy my life (I'd more than likely loose my kids because of the nature of my job/ We'd all be financially fucked)
 We both know that our marriage is not great, we recognize that but usually put it on the back burner because we're so busy. Plus, due to her upbringing she's not  really supportive of the idea of divorce. 
  But We argue constantly, nothing dramatic just consistent. We've both kind of let ourselves go and I find myself looking elsewhere. I'm sure she does to. 
  I understand that having kids exposed to this type of relationship isn't ideal however I took this job and moved our family to a different part of the country to a much worse environment in the first place; us getting a divorce would only lead to her taking them back.
 I also understand that being in a marriage with someone and not being happy with it isn't a good situation for either of us but sacrificing my kids well being and stability for some abstract idea of 'happiness' seems like a terrible idea. 
  
 Give it to me straight Reddit. Am I complete piece of shit?
