Roommates boyfriend started staying at our apartment 5 days a week and his place on weekends, I feel he should pay a portion of rent, we have had a talk, because he helps himself to things like the keureg coffe witch is mine and to go cups he does not just take a coffee to go he take the whole box of coffe for his place and does not replace. I told the roommate that I will just deduc it t from the rent. She is now talking about putting me out of the apartment with a three day notice, I pay all bills and rent on time never late. What can I do, I cannot afford to move right now. I live in the state of Florida.

You better start saving the money, and making arrangements. She won't put you out in three days... but she can do it with two weeks notice in Florida.

And until then keep your coffee supplies in your own room.

If your name isn't on the lease, then you are renting from her, not her landlord. And she can put you out. With the proper notice.

If you cannot move, and don't want to be kicked out, then keep your stuff in your room. I would be looking for other living options.

First, I'm guessing its your roommate's apt so you are her tenant and she is your landlord. If you do not pay the agreed upon rent in full on time, then your rent is late and she can give you a pay or quit notice which is 3 days. If you don't pay what you owe or vacate, then she has to go to court for an eviction order. But she will get it. In Fl she can give you notice to vacate at least 15 days before the rent is due. Again, she still needs to go to court for an eviction order.

If you don't like her boyfriend taking your stuff, then keep it in your room and put a lock on your door.

... I feel he should pay a portion of rent. ...

Actually, no. Your "roommate", as others have guessed, is the actual lessee, and you are sub-letting from her. She is responsible for paying her rent, not you (although you definitely are responsible for paying her what she and you have agreed that you pay her). Thus, whether her boyfriend pays her rent (as another sub-tenant) is not any of your business.

AK is right, but that doesn't mean he can use your personal property without permission or reimbursement. But if he does after being asked not to, then you should keep your personal stuff out of public areas.
