Hi, thanks for replying

Sorry wasn't sure how much detail to put in first thread
As far as the facts, ex started having addiction problems in 2009 that continued to escalate and he was asked to leave the marital home in
2012. I was a stay at home mother from time second child was born and went back to work full time when they were 12 and 14 as I knew marriage would be ending. Prior to that he worked and was gone most days of the week 14 to 15 hours per day. He lived at his brothers rent free from time he left until fall of last year. Youngest graduated in 2014. Ex has recovered after a near death experience in 2013 and fully free of addiction now. I understand , the youngest is considered an adult, however, morally, he has had some issues due to the circumstances with our family life and has been slow to mature , but is on his way now, and ex has agreed to continue to support him for the time being. Ex has paid the standard amount required for child support on two kids since he set up own bank account in 2013.
Oldest is in 3rd year of four year course. He may take additional 2 years after 4 year course to expand degree but hasn't decided yet. He works in summer and pays full tuition, books etc himself which takes the entire money he is able to earn in that time frame.
I have high school and ex has taken various job related courses over the marriage and is now in senior role.
I know the kids are adults legally, I just say sole as they have never, even while minors, stayed with him overnight except for one vacation last summer. Sole I guess comes from figuring out the child support.
The kids and I live in the house, the ex is living with new partner effective last fall in her house. Her child is grown and gone. New partner makes more than my ex and.border in basement so probably no mortgage on the small home.
Marital debt is $151,000 home. Ex purchased $36000 truck in 2011 without my approval on mortgage line of credit which I probably can't do anything about. He took that truck in spring of this year and sold it at $16000 dollar loss with the understanding that the money would be put back on marital debt until all was settled. Instead, he took the profit and put it on a new truck , therefore , I am partially paying for new truck, in my opinion, as I pay the mortgage.
We had decided I would stay in the home until oldest was done school and then I would decide whether to sell or stay and divide then.
I am not out for blood, but do think he should have been and continue giving enough to cover child support and the fact that I pay all marital debt with the exception of the water bill.
Has he not been responsible for covering half of mortgage payment and house insurance as well as child support until an agreement is reached!
Child support for youngest would have just become a non issue in July of this year as I am in New Brunswick and age of majority is 19 here.
I understand this is all delayed 3 years, but our circumstance is that my ex up until the fall of 2014 was in the throws of addiction and then in recovery process. It has been very painful on both sides..and we are just getting around to it now
