my husband cheated on me damn near the whole marriage with different woman will I be able to get alimony from him, and how long will I be able to get it.

The amount and length of time you receive alimony depends on your assets and the length of your marriage

You would need to hire a divorce lawyer and need to see what assets your husband has or is hiding. Usually your case is in your favor if you can get the right Lawyer. As for how long if could be a about six months before it goes to trial or sooner if settled out of court.
