Lyn .....
Although I do have a supportive spouse, I just wanted to add that we are all here to help walk you through the coming months! Also, some spouses (male or female) just never grow up emotionally and when their mate goes through a rough patch in life, they cannot handle it. Many of these types of individuals were always the focus of everyone's attention, some starting with parents ..... and when attention is diverted away from them, they become very insecure and act out in all kinds of ways. Basic human nature should kick in here and common decency should make him compassionate as to what you are going through .....
Even though I personally believe in my marriage vows, there are many cases in which couples should not feel guilt about splitting when it becomes a toxic situation that is unresolvable. If this is the case for you, do what is going to be healthy for you and your children in the long-term. That being said, being in the throes of the AN crisis is probably not the ideal time to make a permanent decision for the long-term. Lean on the support of your mother and friends (and us!!) to get you through this crisis before tackling another potential one.
Thoughts and prayers.
