Last time he was joking around with me and told me his wife called him and he started laughing and was like "just kidding", I just wanted to see your face". He laughs about it with my friend, and he laughs when I get jealous about another girl. He told me " you think I mess with other girls and I don't". We aren't in a relationship, we are just casually dating but I can tell he really likes me. He also asked me before having sex if I'm having sex with anyone else, he has asked me that twice already. Is he testing me?
