Help please! Advice

Me and my boyfriend keep fighting all the time! We're fighting because he's mad about me talking to guys that want to get at me and that I don't tell him everything. Too me as long as he trust me to not do anything with the guys it should be no problem right? And I only don't tell him the little things he does because there little to me I may not care for it to much but I don't mind them. I just vent to close friends. Help with advice to find us common ground!
