Everyone likes my new bf?

but I feel he does so many things that annoy me but he is super sweet... do you think the annoying things will become obsolete or am I just not into this guy, I am 27 he is 30.. little things like the noises he makes when he eats... slurping alot at a fancy restaurant.. singing in the car while me and my friends are trying to talk... i know its petty but I get annoyed with it.... what do you think I should do?
