And it is quite natural for the landlord to meet this girl. Actually, in this case, you tell him that if he doesn't agree, you can tell you that we are not suitable or something. There is no need to delete you. If you delete it directly, you can see that this girl is also very direct.
Suggest that the landlord give up. He doesn't like you at all. If he really likes you, or likes you a little, he won't delete you. If you have disappeared from each other's friend list, let it disappear. You probably can't. This kind of girl is not worth pursuing. At the very least, you can't stand catching up with him.
