I agree with you. The most important part is that, the lines of communications between you and him have been mutual, open and accepted. You know your boundaries and you know how to deal with this maturely. Stalking/harassment is easily thrown out in verbal context these days and in forms of writing, which shouldn’t be taken lightly. So when Anita mentioned it, it’s very important that you thoroughly understand the acts/behaviors of it. Especially defamation of character, so take what she said lightly, according to your situation but be aware of the definitions of them, in case you made need to know the signs in the future.
