i am bad at managing my emotions!! ahhh!!

So I got into a romantic relationship with my current partner about a month and a half ago. Its been going really well, and we get along perfectly fine! Lately (last 2 weeks) though we havent been spending nearly enough time together and it makes me doubt my feelings in the relationship, and I have a crush on a boy in some of my classes at school, ans we are becoming good friends! I just dont know what to do at all, because I dont want to do anything to hurt my current partner, but I also want to feel more fulfilled? I am entirely unsure.
