Was i being clingy . ??? is that why he ended it .?

Ok . Well me and this guy let's say his name was ene . Well we've liked each other for a while . Ever since the beg. Of the 2nd semester . And well . We barely started dating during the summer . So we're dating everythings going fine .he even told me iwas his wife . But the next day . Iwoke up one morning (pms) and well since he's a senior now and I'm just a sophomore . Iasked "why would you be worried abt. Me ., you're a senior now . So why ., and how long do you plan on being with me .?" And he replied "uhh what " then isaid "yeah ithought so nvmind" then he said "ooook" so. Isaid "yeah watever" but then like a hr. Later isaid "I'm srry" . No response . Then a few hrs. Later isaid " ene plz tlk to me isaid iwas srry" then he said "huh" then iasked "your're not mad?" Then he said "no. Ijust realized we have to stay friends for now at least" ., my heart dropped and I cried like a baby . So my question is was I being too clingy ., or was I being too dramatic for him. ?? What sparked the break-up ., and if any hope. Can iget him back .because ihavent went one night w/o cryin for him. Longing for him., missing., him ., and thinking abt. Him. Someone please tell me . If he still cares . Please ithink imight be in love with him . Please iwould greatly appreciate it . And please be honest . P.s no mean responses . Because I'm already heartbroken . Also idon't want anyone else but him . What does that mean.?? Srry it's soo long .
