Input: We bought a new house earlier this year.  It was extremely dated (late 70's - 80's style) so I did a lot of work (by myself, for about two months) to update the house before we moved in.  My husband's friend made several comments about how he liked the decor better before I painted/remodelled.  After about 10-12 comments of that nature over the course of several weeks, I finally told him that he is quite welcome to decorate his own house in any manner he pleases and "thank you for voicing your opinion!"

He stopped making rude comments, but then he started nicking up the doorways with his bag each time he came over.

I asked my husband to speak with him about it because I really don't know him - he is a recently made friend my husband.

I thought it was resolved because he became "overly" nice for a week or two ... But it wasn't long before he started "teaching" me things about my job and eventually asked me for an introduction to a very busy colleague so he could make a complaint for the purpose of getting something from their company for free.  When I told him that I didn't have the information he wanted, he accused me of gatekeeping and bullying him.

I asked my husband to ask his friend not to come over anymore.
The friend didn't even ask why.  He just said "wow."

Am I the asshole?

I'm a woman, if that wasn't obvious.
