So how do I figure out what he wants?

My boyfriend has told me let's take things slow see where it goes etc because he thinks one day we won't be together because he believes he only is meant to be in my life to help me get everything together.

Well his step dad and more family members told me that my boyfriend isn't gonna allow me to go anywhere because he loves me and enjoys my company and such which he isn't a bad guy just damaged from his past relationships I am helping him learn everything as far as how a female should treat a man etc but my question is why is he saying let's take things slow to me but tells his family he basically sees a future with me it's very confusing.
