This was really interesting post I have to admit.
Firstly, there are so many guys out there walking like they own the world and thinking every girl should be in their bed..
Also, there are girls that wants to find a guy who would be their sponsor with buying things..And they are true match for each other..That is just kind of mindset I guess..
Secondly, why are you even helping your friend by telling lies to those girls? I mean.. nice gesture to help lol, but if a girl needs you to tell her the guy loves her, I think she is stupid.
When a guy loves you, you don't really need anyone to tell you that, he shows you and it's simple. Of course, a man would do anything to get what he wants, but girls with even a little brain knows which one wants just sex and which one is looking for love..
And with the last part and math part,you totally have right!
Have a nice evening :)
