17 & Engaged

My SO and I have been together for two years . He proposed to me December 30th I said yes . I love him more than anything in this whole entire world . Only problem is I've not told my parents, I feel like they won't approve or be supportive . I'm 17 but I turn 18 in July then off to college . My parents are controlling I think they would try and make me call it off . Any advice ? Please no "you're too young posts" we are going to wait for two year before getting married .
