If he has the same mindset as you, talks badly about her, or says things like, “she should have respected herself,” then, no, he didn't treat her with respect.
If she wanted to be exclusive and he did not, that's fine, and it happens.
My question is why do you seem to have such a negative view of her for simply dating him and having feelings for him? From my point of view, it sounds like you are trying to put her down to make yourself feel better. That's not cool.
Enjoy your relationship and let her be. Stop with the childish behavior.
You could send her something like a present or write a card. Something that is clearly flirtatious or romantic.

How about a foursome? With another couple. Then there is someone for her too. Otherwise this is just all about you.
