feel like ive back slided!.......

Been really strong for last 9 days of no contact with my ex but and hes been constantly in touch for last week giving me abuse on how im using our son as a weapon, becoz i have not responded to any of his msgs or phones calls he does have set days and times to see our boy. However, my boys been really poorly and had to take him to hospital today, and i thought i should really let his dad know as it was quite serious..... Absolutely nothing back!!! I no i shudnt want a response back, but im obviously getting the silent treatment for ignoring him all week, but i really thought he should know today as it was serious, now im home i just feel angry and want to tx him again... Ahh this situation is so hard! Least my boys ok thats the main thing isnt it.why do they have to play these games its so difficult Xxx
