I really need advice, my boyfriend has been really distant the past few days. I really thought nothing of it, just tried to give him space but tonight he texts me and he says "bye Kayla". I reply "bye?" and he didn't reply. I messaged him on snapchat and he was like "leave me alone" and I said "okay..sorry" and he replied "bye". he has a history of severe depression, I don't know if I should be mad at him or worried about him. What should I do??? :(
