My emotional spill

Ever felt like your boyfriend or anybody you care about says something so much you don't believe it but until that momment they say it to you with all there heart and mean it.Today was that very day for my boyfriend. I love him even more. Ussually when he says it I just kinda just take it and don't really think he really means it (its quality not quantity). He could say it all day long but I know he really means it and when he is just saying it. Today was diffrent. He looked me in the eyes and held my hands and said I love you. I was tearing up but I said to myself (man up). I find it hard to say I love you without meaning it because being a teenager nothing is forever and we are very on the spot emotional.
