Hi, I am so sorry to hear this. Your fiance, assuming he owns the home, can evict you pursuant to your local eviction rules. Generally, however, this means he has to give you 30 days notice, at a minimum. If you don't leave after that time, then he can file.
No, he need not give you money, nor are you obligated to give him any, unless you have otherwise agreed to, which I doubt. Had you been married, there would have been a legal obligation for spouses to support one another should one need support, (thus, spousal support during separation, during divorce proceedings, and after divorce if appropriate) but since you opted out of the legal obligations and rights of marriage, and merely continued dating/living together, there is generally no obligation for you either of you towards the other and you are expected to be self supportive as an adult.
With regard to stuff you own, or you own jointly, if you two can't come to a private settlement on who gets what, you CAN sue him for return of your property, or value of your half of property, if something is jointly owned. If you have a joint bank account, you can likely take 1/2 out without too much concern, but taking it all out, unless you put it all in there, could ruin your credibility later, if this goes to court.
I suggest you go through the house and take pictures and or video of everything that you urge is YOURs or part yours (things have a habit of disappearing later), so that when you try to prove what existed that was yours, that he denies, you have proof. Feel free to NOT tell him you took the pictures/video, so if he lies in court about the items, you may be able to prove it (i.e. let him hang himself because he doesn't thing you can prove him wrong).
