Ex boyfriend or Boyfriend? ASAP! 10 pts best answer :)?

Ok um so Im going out with a guy i love since 3rd grade, i love him but i think i have more feelings for my ex boyfriend? :( Today at school, when i was walking to my cl, my ex boyfriend(ariel) and his friend(edgar ped by. His friend told me "Hey victoria, ariel still loves you" and i just looked at them and ariel looked shy. My boyfriend gets jealous alot, he got jealous of me talking to my best friend(Alex) on the phone and because he gaved me a teddy bear for my birthday which was 2 days ago. When My boyfriend and i talk online, he asks me if he can call me to my cellphone but when i want to talk to him, my dad is always in the house which is almost pretty quiet and he could hear my conversation and he always asks me who am i talking to and pretty much wants to get my phone and talk to my friend to make sure its my friend.(hes very strict). My boyfriend doesn't believe me and thinks its an excuse to not talk to him. I do wanna talk to him but i always get that bad luck when my dad is around me and he sometimes takes my cellphone with him. My ex boyfriend ariel was a such nice, caring person, he totally showed me he loved me and wants to go back. I think hes even nicer than my boyfriend because my boyfriend is kinda mean sometimes. What He also got me so nice gifts even though i told him not to buy me one ;) What should i do? Should i give my ex boyfriend a chance? Brake up with my boyfriend and go back with my ex? (but wait a while before we go out). What should i do? And if you guys say to break up with my boyfriend, how should i tell him? :(
