As attorney Knudsen suggested, do get a new boyfriend and do that FAST! You can help Boston by contacting your local police department and making them aware of your "new boyfriend's" fugitive status.
Of course, it is in your best safety interests to disassociate with this "boyfriend" as soon as possible. Call our offices should you need additional assistance with this matter. Best wishes!
You should take action to protect yourself. Obviously, I would break off the relationship. You can then contact the local police department to tell them that your boyfriend is a wanted man. Good luck.
