My friend didn't get mad at me checking out her boyfriend, normal?

This strikes me as healthy.

Normal enough. You may even be making her feel proud of what she has.

She’s proud of her man and there’s nothing wrong with you doing a little window shopping.

Sounds like average 22 year olds behaviors, all depends on what you were doing, what you were staring at and if you just looked at him or if you were drooling and foaming at the mouth, etc.

Sure, that's a normal sign of trust within a relationship. She trusts him not to cheat and she knows that other girls and boys are going to check him out and there's nothing that she can do about that.

She just likes him not love him so it doesn't matter if you look cause other girls look too or she wants a threesome with you 😕😕😕

Well was pretty clear with what she said. In any case, if he really likes her, that's all you'll really accomplish.
