Bf raaant 😒

Ohkay so my bf of 2 yrs & some change has been getting under my skin lately, but idk if I'm just being sensitive or not ,but likew wen we go to the store I joke around an stuff & he's always tell me how I "PLAY TO MUCH" not just in stores & stuff but at home too an it gets on my MF NERVES lol it just makes me feel like I'm an extremely childish person an since heS always telling me how I "play to much" I feel like, he feels like he could be with someone who is less childish.. Who wouldn't want to be with someone who has a sense of humor, who wants to be with someone who is Alllways serious, like No ! That's so boring .. Advice? Lol if there's any out there ?Â
