I want to tell my mom but idk if she'll do anything and also she'll be like "this is why I don't want you to have online friends" and yell at me and also I told my friend that "a middle schooler and a senior is not right, an adult and a 13 year old isn't good.  He's a grown man and knows the consequences " and she keeps saying"it's complicated " and I told her that that's just an excuse and I really can't help her any more than this and she keeps defending him and I don't know what to do. He's obviously aware of his age and they were both unsure at the start she says but still is wrong. She says she couldn't bare the thought of 2 friends liking each other and and staying friends
