My girlfriend and I go to different schools. Lately she's been telling me how a guy at her school has been tackling her (playfully) and how he once tried touching her "no no square" with a hand size american flag. And today she told me that he tried lifting up her shirt, which is way over the line in my opinion. He's also been telling her she's sexy and whatnot. I've tried talking to her about it but every time I do, she tells me to drop it and move on, like she doesn't even care. She told me that she's told him to stop, but he hasn't. It kind of seems like she likes the attention she gets from him. Advice please?
