Im always depressed and I also make small arguements with my girlfriend into a big deal. I frequently get into arguements with my girl friend about little things. I have a hard time trusting her about not flirting and cheating on me with other guys. I always get jealous when she hangs out with guys. I get her mad when I tell her that I assume things like shes flirting with other guys. I make small arguements into a big deal. I need advice what to do.
