How to leave stuff to people after you die?

Hi, i just want to know if there is a way to leave instructions for how you wish to be burried after you die? like instructions on what u want to be burried in?

I have ovarian cancer , and i have like 2 lumps in the back of my neck as well. I was doing some natural therapies for a while that keep me in pretty good condition considering everything.

I met a great man about two years ago and we had a long distance relationship , he was in the army , i forget everything bad and had hope for my future as i had him , he was in Afghanistan an i needed to take care of him over there and things were good . He came home and dumped me, ( my own fault)

I never told him this nor my family , he was going through alot and i knew deep down we couldn't last ( my fault). Why add burdon or try to keep him in guilt or screw up his life you know.

My question is if i died is there a way he could be alerted ? Is there a way i could leave instructions on that i want to be burried in his tags? And a few things he left me? And i want to leave him my fathers copy of the congress of the usa, its old an he admired it and i know it would mean alot.

I can't tell my family to alert him because they never met him. I don't have alot of money so i can't afford a lawyer unless he whips something up fast. What's my best option for everything i want to do? Do i go to a lawyer an tell him what i want left to each person and then give the document to a family member?

We had a bitter breakup an he hates me now , i have a tattoo of him on me if it helps?

If anything were to happen to me i would want him to know and get some things.

Please let me know what my best options are and cheap ways to get this acvompished.

And don't think im weird lol if u knew him you'd understand why i feel like hes a peice of me . And this is just a in case ,not saying im croaking lol just want to get my ducks in a row , im doing ok right now physically with what im doing .

Thanks.
