I thought he was falling in love with me, why did he let me go so easily?

You cancelled your date together and then refused a second option because you said you would rather watch TV. Even if I loved a girl, if she said that to me I'd probably drop it right there. I can't believe you were shocked at this, he said he was falling for you and you said 'Nah, TV is more interesting to me than you are'. The only way you'll get him back is of you apologise for being an idiot and then explain to him what your issues were with the relationship. playing silly games just hurts peoples feelings and will end up with them moving on to someone more mature.
