Belle,

Trust issues are difficult to overcome. I have my own trust issues, but my friends do their best to listen and try to understand. Have you tried talking to your BF about these problems? Maybe if he doesn't at least try to understand or even care, it may be best to end your relationship with him. If he's not willing to cope then he doesn't deserve to be in a relationship with you. Perhaps breaking up would help you with your trust and jealousy issues.
