Should I ask a friend If he got my THANK YOU note?

Yes. Just bring it up casually.

Rude, Thank you notes regardless of how lengthy they are fall into the catatgory of things you just don't bring up. It makes you look like you didn't honestly mean what you wrote and just wanted to make yourself look good. Its a prick move regardless of what your honest intentions are and I would advise against it

It's just a "Thank You" note...why do you need to know if he got it? Sounds like you may like this person, thus you want to contact him....it's up to you. I don't see the harm in it, although I think you should wait for him to acknowledge the note first. You did your part by sending it. BUT if will clear your mind, go right ahead....

That would be weird and almost thanking him too much. If he gets it, he will say something or acknowledge it somehow. You just need to be patient. Maybe he hasn`t checked his Facebook, or has been busy and side-tracked. Chill out.

First and foremost, I need to make this perfectly clear. Zayla is a stupid ****... this person knows little to nothing about anything.

With that said: you will come off as creepy and weird for asking about the note.... dont ask about the note

Ask him, it's only normal to get a reply on facebook.

It wouldn't be rude. You put effort into it and that's the only way you'd know he got it.

No, don't ask. There's no reason why he wouldn't have gotten it. But do you want him to say thank you for your thank you? Then you'll have to say thank you for thanking me for my thank you....and it never ends? Just kidding but leave it be.
