No I don't think that it was all about sex, if it was he probably would have tried it on a long time ago and he would've stopped talking to you when you didn't end up meeting - I mean you spoke for a year and a half!!
But the fact is, he said he's got this whole "no virgins policy" thingo ; so, I guess maybe he's backing off? Why do you want to stop speaking to him? You never know, he could be confused because he likes you - who really knows. Have you TALKED to HIM?
To love is to suffer. To avoid suffering, one must not love; but then one suffers from not loving. Therefore, to love is to suffer, not to love is to suffer, to suffer is to suffer. To be happy is to love; to be happy then is to suffer, but suffering makes one unhappy; therefore to be unhappy one must love or love to suffer or suffer from too much happiness. I hope you're getting this down.
