arguing

me and my bf argue kind of a lot mainly because he's so insecure and can't even trust me enough to go to the bathroom alone idk why he's so insecure well ok I do his past gfs cheated on him and I'm like the best thing since slice bread to him I'm far from a lazy girl like his exes well anyway he does give me the world take care of me n my son but I tell him to stop fussing in front my son (5yo) it's not his child he don't listen he always does it and earlier he told me to STFU in front of him
