If your sure you don't mind this is what I've picked up. Don't feel bad though English is the only language I know and I butcher it terribly. It's impressive that you are as fluent in English as you are in Swedish.
...You know his more - This should be “He's” as in short for 'he is' rather than his which indicates possession.
...got of the sofa – This is where it should say “off”
...but that didn’t stop John for slamming it shut - Should read "from”
...taking of his jacket – As mentioned another use of 'of' rather than “off”, my apologises though on closer inspection you've used this word correctly most of the way though.
...And I like to leave right now. - I think you mean, and “I'd” like.. as in short for I would, but it could have been I ”need” either would work.
...and let go off Clara’s hand. - this one should be “of “not off this time
...if he didn’t watched for cracks - this should be “watch”, this is present tense, watched is past tense. Tenses are tricky little buggers.
...“It been better – “It’d” been.. for short or of course “It would” have.. for long
...No wonder John wanted him .. - This is referring to a past event right? In that case it should read John “had” wanted.
That's all I can see. And I assure you if I was writing this I would have made several more mistakes, but you did ask for examples so I hope you find this helpful.
