Hello Gina,
I was just wondering if your husband has shown that he loves you other than just telling you in letters, or on the phone.  I hate to say this but "talk is cheap".  You have to be "dead certain" that you are not being used as a means to and end, otherwise you may find yourself "dead for certain".
Just my thoughts, I would hate to see you being taken in by a felon.  Do you know anything else about his criminal record, or was bank robbery his first.  What about his family ?
Chat later,
Steph
