Hi mb. I'm glad your son is doing well. And I pray he is given the green light to go home soon.
As for H I know it's hard, however you can't dwell on it. This shows his true character. Mad at you or not to me it is totally unacceptable to ignore a sick or injured child in the hospital. I find it disgusting. No matter how angry or done with W I may be. If I get a text that a a child is in the hospital I will find out what happened. If it is serious like in your case where I am needed for the child I am there. To hell with work and anything else.
Please don't try to mind read. It will drive you insane. I see his apparent dismissal of your texts and calls to inform him is like I said a sign of his character.
This is a tough time and myself and everyone here are here to help you as much as we can. Stay strong MB and hope to hear from you soon
The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
