Never perform a strong emotional action through e-mail, which can be cold and impersonal. Meet them in person (perhaps even with the bf not present) and tell them how wonderful it has been spending time with them. Who knows, you may be able to drop him and keep them. :o) Good luck!

face to face meeting, explain your position give hugs...go on with your life you deserve better.

It would be nice to keep being friends with the family, but it would more than likely serve to upset the ex. you don't want to rub salt in his wounds email them and arrange a visit at like a coffee shop or something. if/when you meet them in person, make sure mention that you want to keep in touch with them (if you really do), and why you're breaking up

I am in a kinda similar situation. First I will tell you. I am very close with my ex's family (his mom's side) and I am talking the whole family(uncles, aunts, cousins, his brother etc) I was even at his mothers wedding about a month ago. Him and his girlfriend where there, i was in the front row they were sitting in the back. Diffrence is I have his kid. I met him when i was 19 and i am 28 now so we had an on again off again relationship. They all hate the currernt gf and love me which makes it hard for her, but i guess it doesnt bother him at all, but then again I dont care. Me and his mom have always been close and supported each other threw some of the stupid shit that he has done. Here is what you should do. Whatever you want. Of course I think he should be comfortable with it and as long as they are ok with it and you guys are over and this is in no way a plan to keep him in your life you just want to continue your friendships with them. If you do decide to to say goodbye then do it face to face. Send an email to the one you are closest to and even if you cant meet with everyone at least meet with that person. Dont explain why you are breaking up because that is beside the point just say you decided to go your seperate ways. Make sure that you do tell them that you would like to continue a friendship with them but only if it is not awkward for all parties involved
