Not to tell DH that DS crashed his bike?

[ThisIsTheGoodPlace]

Name change as DH knows my usual name.
DS recently purchased a piece of junk motorbike (More like a glorified hairdryer). There was a lot wrong with it and DH said that DS was not to ride it until we took it to a reputable garage.
Predictably DS didn’t listen and took the bike out and fell off it. He wasn’t badly hurt but the bike is in an even worse state and he has quite a few scratches and bruises.
DH is away with work for a few days and I’m hopeful the worst of DS’ injuries would have faded by then.
The issue is complicated by the fact that DS is adopted and since reaching his teenage years and developing a relationship with his biological father has habit of throwing this in DH’s face which causes a lot of upset all around. I’m pretty sure that when DH finds out and gets cross with DS the usual upset will ensue.
AIBU by not telling DH to save further upset?

But won’t DH see the damage to the bike when he returns ?

DS lives away for uni (Only an hour or so away) and the bike is kept in a garage there.

Yabu. How would you feel if your dh hid this from you?

YABU. It may seem like a short term fix but you shouldn't keep secrets from his dad, your husband.

Surely he'll notice the bike is damaged ... ?

Well, he’s an adult, so I don’t think I’d tell DH. I’d encourage DS to tell DH himself - would DS be able to swallow his pride and let his dad know that he now accepts he was right?

DS is an adult then, and can make his own choices about the bike?

Your husband is his dad. He should be told.

Are you seeing a family therapist to deal with your son's behaviour towards his dad now that he's met the biological one?

I don't think I'd keep that from DH, to be honest, because, I wouldn't want him to keep it from me.

Is there a time/way to tell your DH to prevent a blowup, say when he's home from his trip and had a day to settle back in? Talk to him about how his reactions could really push your DS further away and that you need him to keep a lid on it for your sake.

You don’t need to tell him. Your DS is an adult. Leave it to him.

Your DS was told not to ride the bike until it was checked out which is good advice isn't it. he then rode it and fell off. as your DS must be 16+ then really he should be taking the consequences of his action. if anyone is to tell your DH what has happened then it should be him. was he insured at the time? perhaps you and your dh shouldn't insure him on the bike until its checked over properly. Your dh needs to control his temper. getting cross is what your ds wants him to do, so he should just say " oh right you fell off. well there you go I did say but its up to you" If your DS is old enough to be out on the road riding a bike then he is old enough to make his own (sometimes stupid) decisions.

DS should tell DH himself. He’s a grown up.

YABU

Letting a teen think that divide and rule between parents is even remotely possible is a recipe for disaster

I wouldn't tell DH. Parents don't have to share every bit of information about their kids. I certainly didn't tell my DH some of the things my DC got up to at the time. Maybe later when we could laugh about those things.

We have been to family therapy but the up heavel of uni seems to have brought it all back to the foreground. I will speak to DS about telling DH but will probably warn DH beforehand so he doesn’t get cross with DS.

Why shouldn't your husband get cross with your son though? Presumably it was a stupid thing to do.
