Is it true love and does he mean everything?

Im 15, turning 16 in July. and my boyfriend is 14 turning 15 in august. Ive known him since the end of last year and we have become wicked close. He is very mature for his age, he knows a lot and he is very sweet and caring. Ive had a lot of boyfriends, but i believe this is my second real relationship, but first true love. I know im young and i dont want to hear about how young i am and how i dont know about love, but i know what it is. I just want to know if this is actually real. He tells me how he wants to grow old with me and spend his life with me, hes never said that to anyone and i have proof that he hasnt. My last real relationship, the boy said the same but he didnt seem sure. My boyfriend right now will do anything for me, he goes out of his way to make me happy. He talks to me about anything, and if something goes wrong (which is rarely) he talks it out with me and fixes it. When im upset he holds me and doesnt let me go, no matter how much i try to break free, he still holds on to me, stroking my hair and kissing my cheek whispering that hes sorry. Also, when we argue, he refuses to stop talking until we resolve it. He tells me he loves me all the time and does absolutly anything for me. He puts heart into everything and makes sure he is free every friday to hang out with me. His mother talks about me to his family and says that im definatly 'the one'... well i have this feeling with him that ive never had with anyone and i am so comfortable with him. its only been a little over 4 months but we say "you dont gain love, its already there, you just have to find it" he doesnt ever seem like he tries to back away when i talk about stuff, he helps me with everything (even my 'girl problems'/ rough childhood) he grew up with all girls and his mom has a wife so i think that may be part of why hes a sweetheart. well i know this is long and thank you for taking time to read it, can you guys please give me your opinions? i feel this is love but i dont want to get hurt. anything will help, i just dont want the "not knowing what love is" nonsense
