So me and the guy I use to date have still been involved with each other. Even though we aren't in a relationship. When he found out I was moving into my own apt he's been treating me different and acting funny. He asked for his house key back. Mind you I moved out his place a year ago but have always had the key when I come stay some nights it never been a problem but now all of a sudden it is. Am I crazy or do y'all think he's mad, jealous or what?
