Living with my bf..

The beginning of last month i moved in with my boyfriend after only being together a little while. We also work together and we ended up getting corona so we were out of work together for three weeks. During that time we were perfect and there was nothing creating any tension. But as of recently he’s been pretty impatient with me and we had an altercation at the store. I ended up stepping on his shoe in anger and he shoved me away from hard as a reaction. Ever since then we’ve been finding stupid petty shit to fight about. Also he’s been hard to talk to as well because he doesn’t like to express his feelings a lot especially when he’s angry so he ends up being defensive and saying stuff he doesn’t mean. I love this man a lot and he’s my best friend. I just wish i knew how to get us to stop arguing so much because i appreciate the man with my whole heart. He took me in when i had nowhere else to go and i really want to figure out how to eliminate the conflict
