Just watched "Lars and a Real Girl" ... it kicked ass. Very humorous film that was quite touching as well. Scroll for spoilers.
Dude becomes dellusional, gets a sex dolls, starts to date her (never has sex). Once he starts coming back around to the real world the doll gets sick (he thinks she is real) and eventually dies. The whole town goes along with it, just to help Lars out.
Check it out.
