ER last night

It has been a rough few days. Friday morning I had to pick up the seven year old from school because he had a fever. Friday afternoon I had to take my little girl to the hospital for a sever allergic reaction and had to deal with problems with that all weekend. Then about five yesterday I get a call from wrestling practice to take my son to the ER for a broken nose.
I have been eating so badly lately. My hubby and I have had problems for years and I have moved a few times but he always follows. He is very negative an bitches about everything all day. Some days I am mentally and physical drain by the end of the day. He is also very jealous. He yells at at the kids a lot. He is not abusive. I know he love me. I really what my marriage to work. I just don't know if I am doing more harm then good by keep the marriage together.
I can tell when I am stressed. I start shedding hair like crazy. I gain more weight.
I never married the father of my oldest two boys. We share cusity and it seems to work will. But I think that is why I keep put the pieces to my marriage back together.
