About my boyfriend trust issues

I guess it depends on what you fight about.

There really isn't enough information to give you an answer here, you should go into more details since there really could be a lot of reasons why you are fighting.

That all depends on what the fights are about. If he is questioning every move you make and asking things like who? why? what? where? when? how long? and you answer even answer them all then you find your cellular phone ringing off the hook with him asking the exact same questions every hour that your out then chances are he doesn't trust you. You should really talk to him and find out what his issues are with you going out and when they started. tell him exactly how it makes you feel when he acts that way
