<human>: I'm 19, and my boyfriend [M] and I [F] have been in a relationship for over 1 and a half years. I know that once this all blows over I'll still be young and there will be someone out there for me. But despite all of this I can't help feeling that he really is the one. Our relationship is amazing, we talk constantly, appreciate each other, and do things with each other without any constant strife or bickering. Yesterday I told him that I loved him, and he said, "I'm sorry but I don't think I love you". He said that he's searching for a certain feeling and just doesn't get it with me like he did with his first crush, and he can't see marrying me. He and I both talked about it and cried for about 2 hours together because neither of us really wanted to say that we were breaking up and through it all he kept saying how much he enjoyed being with me, how much he cared about me and how I'm the best friend he's ever had. But he doesn't feel like that is love. I know that I love him, and I would love to spend the rest of my life with him, but not if he doesn't love me. I'm just worried that we're throwing this amazing relationship away based on something that isn't 100% and that we're both going to regret it.

Give me the gist of the text in a nutshell
<bot>: Boyfriend says I'm the best friend he's ever had and that he cares a lot about me but doesn't think that that is love.
