What would do about this incident?

Ok heres my story. Just about three days ago, my husband and I had our 18th wedding anniversary. We always usually go out and eat just the two of us while the kids stay with grandparents. Ok so i was getting ready to go out and was taking a shower, when he burst into the bathroom and told me something was wrong with his mother, I said oh my no , something serious? I said tell her i hope she will be ok. told him to go and see what the problem was. Ok so i continue to take the shower and then i got out and immediately got my robe on off course and went to the phone and called his cell phone number. When he picked up i could hear that they or he was at a resturant and i knew this because i overheard some woman asking his father what he wanted to drink, i said Um Where are you? he said oh , well um mother is ok just a false alarm and so i thought it would be nice to take her out to eat something. I thought well i guess that is nice but it is our anniversary night and we do not have enough money to eat out two times in one night , so i asked him , ok should i just call my parents and tell them that we are postponing our dinner tonight? and then he realized oh my god ! tonight is our anniversary. I said yes it is . So he hung up on me , well time went on and i am a diabetic so i have to eat by a certain time of night or my blood sugar will go low and besides that the kids were getting hungry by then also. I called and cancelled things with my parents so they could go ahead and eat also. He did not come home until three hours later and i was almost ped out , i did not eat much because i thought we were still going out , he never made that clear , i also thought that by that time and since they were eating out that he would at least think of me and order me something to eat, he did not. So anyway, i almost went into a diabetic coma by that time i was late for my insulin shot and needed to eat something fast, so i went and got some orange juice to get my blood sugar up , me not him now and then i had to eat a cold sandwich and drank water , there was nothing else there to eat . I gave my children pizza , i can not eat that at all. I was so sick and just wanted to go to bed and all he could say was , man that fried catfish we had was so delicious , you would have really liked it . Now what would you have done ? What would you have said? I mean , scare me like that , his mother is a diabetic also but guess what she came first and he was very aware of her needs and forgot mine ? I felt like screaming and would have if i had felt like it but i was so weak and hungry and tired that all i wanted to do was go to bed. he just sat up and watched baseball after that, never came in there to see if i needed anything or was ok. No and he stayed up until 12:30 pm. I also found an email that he sent an woman on a chat room. I still have it but he does not know i have it. What should i do? Did i deserve this in any way? I could have died before he got home and there was nothing that the kids could have done for me but watch me die.
