Should i break up with him?

k so me and my boyfriend have been dating for almost 4 months, and during that time when we hang out its mainly like making out and dirty stuff but theres no spark at all, i mean theres definitely wetness down there if you know what i mean and a ***** but theres no like high giddy magical feeling love or like is supposed to be like. it feels dry, i mean its fun to be with him, but its more like were friends with benefits than anything. however, he's the only guy that can make my heart feel like this, ****when he and other girls talk i feel jealous and like if on facebook theyre having a friendly convo id feel like a pain in my heart, plus ive cried cuz he was being mean but not on purpose, and everything a girl does with him like say he says hes gonna go to the movies with another girl my heart HURTS. if i didnt love or at least like him it shouldnt do that right? plus were so compatable we like the same stuff and have the similar habits, but then again friends could have that too. right now at school i notice other guys and i swear i get butterflies when this one guy touches me. this shouldnt' be happening if im in love with my bf right? i just now realized, and i myslef think my bf is ugly thats not good for a long term relationship....help, should i break up with him? he seems to really love me i dont wanna hurt him and if he gets over it and dates other girls id be hurt to see that too....HELPPP
