I give him whenever he wants but he still watches on the side.. I want to know why.?

It won't work out. I've known several couples with similar issues and once the girlfriend tried watching with the guy then the guy wanted to watch all the time even while they were having and the girl got tired of doing that after a while or if you try to force him to stop he'll hide the fact he watches it when you're not around. Whatever the case, it's not going to work unless he really wants to stop watching it on his own. Sometimes they are just addicted or they can't get off unless they watch it.
