If he got hit on the head due to his own stupid actions, your husband needs to tell HIM to watch what he is doing and I would tell him as much.

He's 14? I was going to guess 8 or 9 before you put his age in there.

Your SS-14 melted for so many hours because he could. You have a step kid problem and a DH problem. Funny how they decided it was your fault because stepmom is always the easiest one to blame when something goes wrong. 

Getting hurt happens sometimes you have to pause what you're doing to deal with it He could have just gotten some ice and you could have gone on with your day. Instead he made it all about him for the rest of the day and tried to turn your DH against you, that's too far. I swear step kids will use any little mishap like this to turn you into some sort of enemy. Your DH took the bait and ended up shunning you for the entire day. What the hell is wrong with him!

I was feeling bad for the poor tyke until I read his age. Before I make the comment that's bouncing around in my head, is this young man special needs or developmentally delayed in some way? 

While I wait for an answer I'll say one thing: you apologize once. That's it, not over and over. And get out, go about your day and leave the two of them to get over themselves. Dang. 

Sounds like SS didn't really want to hike and needed an excuse.

And he's angry about something else and/or desperately needs attention so he used this opportunity.

Ultimately your DH is a d!ck who is coddling his almost adult child and has trained him to act like a giant baby, at your expense.

Trust yourself.

OMG, seriously? I hope you took the dog and went for a hike by yourself.  What a dysfunctional pair SS and DH are.

Hands up anyone who would've gotten a second whack over the head for being a teenage idiot running under a closing hatch if they were SS. 

Before you gave his age, I would have guessed six or seven. By the age of 14 you should know better to do whatever SS was trying to do. 

DH needs to brush up on his parenting skills. If this injury caused SS so much pain that he was incapacitated for hours, DH should have taken his son to the hospital or urgent care to be checked. SS should have at the very least been lying in a quiet dark room with no screens until the pain abated. 

DH also needs to brush up on his husband skills. You don't blame your spouse for an accident that your child caused. 

Next time the three of you are going somewhere, DH loads the car. 

They are both dumb, please tell me you still went on your hike with you doggy that likely deserved it for putting up w/the idiot skid. 

You should be pissed off at both of them IMHO.  A 14yo acting like a toddler is pathetic.  No blood, no indications of a concussion, then GTF over it and hike on. IMHO of course.

As for  your DH.. .he is just a child worshipping dickhead IMHO.

I would give them both clarity on how pathetically they both behaved during that event.  SS was a teen boy brain fart driving dumb ass.  He should learn to pay attention to his surroundings and not to put his head in the path of a closing SUV hatch.  Basic Darwin Award stuff here.  If he does not learn, he will save the gene pool from his polluting influence.  Hopefully before he procreates.

Now for your pathetic husband.  smh.  I would let him know that if he ever agains grouses at you when his idiot kid shoves his head in the car door that life as DH knows it will immediately end and his new existance of abject husbandly misery will begin.  Also let him know that your husband will not ever again cater to a manipulating cry baby p#&&+ teen boy who pulls a dumb ass move then cries to daddy and wastes YOUR activity time with your husband with the manipulative tear fest 'dada, take cawe of me' bullshit.

This is incredibly nauseating.

As for whose at fault... DH is.  He is the one choosing to be a dick.

you should have quickly got in another one while DH wasnt watching 

Incredible that a 14 yr old cried for half an hour from a little bump on the head.  What a big girl's blouse!  And your DH behaved really pathetically too.  As someone said - the silent treatment is emotional abuse, and choosing to do that to you because of an accident is beyond bizarre.  In a functional family it would have gone: 

SS:  "Ow!" 

SM: "So sorry - are you OK?" 

SS: "I will be in a moment".    All get into the car and carry on. 

I am completely dumbfounded by your DH reaction. Is he trying to raise a complete wuss. 

I would die inside if DS 13 acted like he was dying after a bump on the head. I would be like suck it up man!!! Heaven forbid he ever does that in front of his peers he will be crucified. 

I always say to DS your mother shouldn't be tougher than you. 

Your DH is a do@che and is raising his son to be one as well. I guess I would question his mental ability if he truly believes you would do something like slam his kids head in a door on purpose...like what does that say about him as a parent?

This actually happened to YSD when she was 13. She stepped under the hatch right when DH was closing it, no warning.

Cue crying and sobbing and her asking him, "Why did you dooooo that?!" Like he did it on purpose. He said he was sorry but it was an accident, and to tell her to watch what she was doing. It took a good ten minutes for her to calm down.

He stepped on her foot once around then, again, she wasn't paying attention, messing around, and she moved in front unexpectedly. Cue same damn reaction and blaming him for the results.

At least he didn't take it.

OMG I laughed out loud reading your post!

I am the mum of two boys (now adults) and they never performed like that!

Until I read how old your SS is, I thought you actually were talking about a child aged 3 to 4...
