from my experience of having my wonderful boyfriend in jail i can relate to your questions. my boyfriend is in jail for five more years and im so excited for the day he gets out. besides that... i was confused what to write at first but just write to him how you really feel while your writing the letter. let him know how everything is going and how your being completely faithful on the outside. explain to him how much you love him and why you do. tell him what your plans are for when he gets out. i tell my boyfriend all the time that i care about him just to remind him im here for him. i also told him that he could tell me anything and that im the only one who reads our letters. send him some unprovacative pictures, that hed be proud of showing off to people walking by his cell. spray his letter with your favorite perfume (that you know he likes) he will love smelling you scent again. just let him know your supporting him no matter what.
