AM I IN TROUBLE?? PLZ HELP

Hi

I am hoping someone can help me. I was chatting with a male friend ( my husband knows we are friends, but my friend hides it from his wife). Anyway, I was saying how bored I was with life etc. He suggested I go to the gym. I misunderstood him and thought he meant I was fat. So I ranted back on the email , being mean and saying ' well we all can't be perfect like you, or your wife'. ( his wife goes to the gym and has lost a lot of weight). I told him that I don't want to be friends since he hides our 'friendship' from his wife. I clicked 'send' . I felt relief. Then 2 days later, the OCD kicked in. I got this thought: ' did I threaten to kill him, his wife and 2 kids???' I know the thought is absurd but I kept thinking maybe I did threaten him since I was angry when I sent the email.

I didn't realise I could recover deleted emails from my Hotmail. grrrr! too late now. But the anxiety was so bad that I emailed him pretending my email got hacked. I asked him if he got any 'death threats' from my email. he said he didn't get anything. I do feel some relief (he might actually think I'm crazy) but anyway, I rang Microsft asking if I can have my emails that I deleted , but they can't do it. I have this fear that I threatened him and now he will go to the police.
I told my hubby, he said that basically he wants me to stop all contact with this man. My hubby also said : ' why would he go to the police when he is keeping this 'friendship' a secret from his wife?????'
plus he said he didn't get any death threats. I just wish I could get back that email I wrote so I can check what I wrote but its too late now

I am worrying for nothing?????
