The GOOD reason he does this, is because he has 2 eyes and an appreciation for beauty. Which also means you must be attractive
Its wrong of you because you reduce him to tears over fictional photoshopped women
Now, If he does it in public to real girls, I can understand (altho I don't have an issue with my bf's eyesight working just fine) but TV?
Really? C'mon, be realistic here.
Also there's absolutely nothing wrong with you, he's dating you isn't he? and he obviously likes pretty girls doesn't he? So I'm absolutely sure there's nothing wrong with you.
Other pretty girls did not suddenly cease to exist when you 2 started dating. What good is eyesight if you are not "allowed" to appreciate beauty???..... Not even on the TV

And just because a guy or a girl looks and appreciates the sight of another, doesn't mean their partners are in danger of being replaced, or are not good enough.
Lastly, and I promise I'm not being mean here. Your jealousy and insecurity is
your problem. Best you work on it instead of making your bf "pay" for it.
