need advice ☹️

My boyfriend and I got into an argument at the mall about stupid social media, it was my fault because I brought it up and was getting crazy, and it was infront of our friend who was with us,  I just got home and I'm so upset at myself and feel like every time I get all dramatic and thing and act negatively that I'm losing him, I have an attitude and am negative but I am really trying to fix it, I can do it. I am so blessed to have him still around and love him with all my heart, he was disappointed in me I could see it. I need to control my anger and relax, Should I text him and apologize or give him his space? ☹️😞
