PLEASE ANSWER THISS I NEED TO KNO ASAP CUZ IM CONFUSEDDDD !?

For some reason when I think of my boyfriend it makes me wanna cry . But its not like its a sad moping feeling . Its like.."Godd I Like Him So Muchh" type o feeling. And i think about him all the time nd when i get off the phone with him i miss him so much .And just thinking of the things he say make my stomach feel all gushy. But a few f these emotions I've had with alot of boys I liked and never loved . The the only way I know I love a boy is when I cry when we break up because I never evr cry over a boy . I've only did that once and it was my previous relastionship . And I dont wanna get to that point where we break up to kn ow whether I loved him or not .So please just give me your opinion on this and what you think it means . and if you can relate to this then please explain it out to me cuz I need to knoww .oh yeah ..im a young teenage girl so yeahh im ery confused .
