Overthinking ?

So me and my boyfriend have been together for 2 years and 5 months these 2 years have been so good yet so rough. He was always so loving with me showed so much emotion and cried whenever we argued meanwhile I was not use to showing emotion and would have a blank face while we argued but I would still explain my emotions. Now I’m the one crying for every little thing if his mood changes I automatically think he doesn’t wanna be with me or when we argue I’m always crying meanwhile he doesn’t show emotion at all. Do you think he still loves me or am I overreacting?
