The other question is... what if he tosses the letter? Are you going to just send another one or are you going to knock on his door the second time?
He's going to be quite apprehensive if you leave an anonymous letter on his door and later on show up in person...
This is just a matter of being a forthright person... people having affairs sneak around like that... people having affairs avoid disclosing themselves and who they are... YOU have NOTHING to be ashamed of and have NO REASON to hide.
If you are forthright he will be more likely to be forthright with you.. if you sneak, he's going to be less inviting to you...
We are making a lot of assumptions about this man's character of course...
We need to find out why you would want to just leave an anon letter... I would take my kids there with me and knock on the door... SHOW him you are not some quack and you have kids and are a serious and forthright adult
