How to rekindle the our relationship? I need help.?

I don't want to make this to long. Please ber with me I am having lots of mixed feelings. Me and my hubby of 10 years are on the verge of divorce. Sometimes I feel like I can't even stand to be around him he gets on my nerves bad. and I am positive he feels the same. In the 2 years we have had lots of tragedy and loss in our lives, includes- layoff, 1 sudden death of a parent, Then a tragic death of a parent, foreclosure of our house, one of us had a broken arm due to a stupid accident and one of us was on house arrest sentenced to 45 days for a minor crime. I know it sounds crazy but all this has happened in a 2 year period and we really are normal people that are really having lots of bad luck lately. We have a 3 year old that we both love very much and we where anticipating the summer coming to go camping and enjoy family activity's together. Last night we got in a big drag out fight and told each other a lot of nasty mean things. He hurt me and I know I hurt him. How can I save our marriage what can I do to keep our family together and appreciate him more and maybe help him to appreciate me? We have been together so long and I want my son to have a normal family life I feel hollow and empty. Thank you.
