my “boyfriend” won’t miss me!?! SOS GIRLS

It’s been a month now since we started like talking, we hang out literally almost everyday tht I don’t work or he doesn’t or that I don’t have school. We are so close and get along so freaking well. Never felt so comfortable with someone. He is comfortable to like grab my ass or smack it but won’t kiss me. He made one joke and said “ I don’t kiss on the lips” and last night he said messing around I hope, “maybe one day I’ll kiss you” I want to know if he actually doesn’t kiss or if he’s just messing and taking things slow because he actually really likes me. I’m so confused. SOS girls
