people who are assuming he is banging someone else are going too far. of course it's a possibility, but there is no evidence to support this. I was in this situation recently with a new chick I was dating and things were happening fast. eventually I found myself really into this broad and in unfamiliar territory - I just tossed attention at her cause I wanted to see her all the time. eventually, and even though I did not want to do this, I had to cut back a bit and play those games.
it's a part of the reality. deep down, she would like me even more if I fucked with her head a bit. it's an empirical truth.
