dating after 6-8 months

So I'm a junior in highschool this might seem childish to many of you but I'm not s girl who dates or looks for anyone but this happened.  I met this amazing and sweet guy we been talking and stuff .. rewind to 7 months ago.. I had a bf and it all went wrong he treated me like shit  .. so now with this guy which is the complete opposite of him.. I'm afraid to even be with him alone for some strange reason.. maybe I'm not used to being treated so nicely.. I know he won't do anything bad to me but my intuition always reminding me of the last guy. I don't even know how to bring him up to my family. I feel like it's early and I need to wait. Any opinions?
