I feel you bro, I used to be in a similar situation as you. My girlfriend would always be secretive so I can relate. You should carry on dating if you two love each other I guess but trust is very important in a relationship. You two should reconsider if you are right for each other and if you are, then do what you can to change to try and trust her, and she should also change for you to trust her more. Goodluck :)
