Wanted sex.

Sent me inappropriate text messages about wanting to find people
also rang me non stop, when I picked up the call it was mostly silence but they were there

I don't know what this guy's deal is but he rings me up to flirt with me and says he recently got my number off some Tinder leak website. When I say I'm not interested he keeps trying to convince me saying him and his wife are "poly" and she would "find it hot". ugh. Gross. Not sure if prank or creep. Sounds about 40. Stay away.
