PLEASE HELP- does he really love me?

OK.. I already have a boyfriend but, there is this guy that likes me, alot. He says he loves me but I don't know. So, here we go.. we started talking a month ago today. We went out for like a day, but I broke up with him cause I just wasn't feeling it. But we continued to talk. He told me that he loves me more than anything in this world, and that he would do ANYTHING to have me. He says I made him the happiest he's ever been in his life, and that I mean as much as his family does to him. We talk on the phone and he BEGS me to break up with my boyfriend. Here's some things that he's said to me.. "Baby we belong together." .. "AVA JANE MATHIS, i love you! Please say yes! (:" .. "You're my everything. You're what I live for. You're the reason I wake up, and what I dream about at night. Baby you're my life." .. "This is real. I swear to God you're my one and all. I love you till the ends of the Earth are back." .. "Baby I would only want that if you would. My heart is yours and I wouldn't do anything to jeopardize our relationship." .. "I'm extremely jealous and I hate the fact that you're with him! I love you. You mean more than anything in the world to me. I'll do anything." .. "I love you so f*cking much baby doll you mean the world to me." .. "You always make me smile :) just talking to you makes me happy. I love you so much and just want to be with you." .. "I just want to say one thing before I go to sleep. I'm not lying at all. I have never felt this way about anyone. I love you so much. I can't even begin to comprehend how much I do. It makes me want to hurt myself the pain is so bad of you going out with Nic. When I think of ya'll I want to kill something. You're the only thing that actually has value to me. If I had to sell everything I have just to be with you I would. I would take a bullet for you. I love you so much Ava Jane Mathis." .. "Ava please pick me. I love you so mother f*cking much it's not even funny. I'd fight all your brother's friends and Nic to get a shot with you. I'd give my life for you to be happy. I know you're confused at who you love most. I promise the right and safe choice is me. I just can't get this problem out of my head. If we went out I would not text another girl if you didn't want me to. I would call you everynight and tell you I love you. Please. It would make me the happiest guy in the universe." .. "Please choose me I feel horrible living without you :( I never told you this and please don't tell anyone.. but when we broke up I cried." .. "I was just looking at the pictures of you and how beautiful you are, and I had to stop because it hurts my heart :(" .. "Ava, you mean more to me than football. And you KNOW how important that is to me. I would give it up just to be with you. (he's the STAR football player)" so, does it sound like it? I'm really confused right now. And also, I was the only girl to EVER get him to talk over the phone. And when we talk, he says the SWEETEST things. I'm just really confused.. please help. and please don't be rude, I really don't need that right now. Thanks
