Questioning a lot

So I've been dating my boyfriend for two years now and I mean he's great, but I don't feel like I love him anymore... like he calls or texts and I don't get the butterflies in my gut sort of feeling anymore. We're kind of long distancing, but he's also been visiting every weekend...

We did make out last night and it reignited the spark for a little bit but I mean it died out pretty fast. We normally have sex on a regular basis but this past week we haven't had any sex at all? Could that have any relation?

Also, not gonna lie but I'm in marching band and one of the freshmen is really cute, very sweet, and has humor really similar to mine. I get more butterflies from talking to him instead of my boyfriend... it feels so wrong but I just don't know what I should do? Is this a sign that maybe I call it quits on my relationship?

FYI: I'm 20 and all of this is college, not high school. Boyfriend graduated in 2016 and is 23.
