need some advice

Ellie
hey ladies and gents, 
im in need of a little bit of advice.
there is a guy that im really interested in and i don't know how to approach the situation. we have done stuff together and had a thing for a while and now we're starting to get close again, but my mom doesn't approve of him because she knows what we've done & i don't know wether or not i should tell him i have feelings still or just leave it alone?
