That's why I have multiple projects because I get tired of one, or one is too fiddly for knitting at knit night, or I just don't like it anymore.
If I decide I must have been nuts that I really am not enjoying knitting something I usually frog it. Knitting is supposed to be fun and enjoyable not a chore.
So if you don't want to to finish it either set it aside and start something new or repurpose the yarn.
