Best friend

My best friend’s boyfriend broke up with her recently and she always says that they didn’t end on bad terms so that she can keep his pictures but she told him that she hates him and that she doesn’t want to talk to him and so they don’t. I want her to delete the pictures and focus on herself because I hate listening to her telling me how much she misses him. I’m really mad that she’s sad and I don’t even know how to comfort her. I don’t know how to be there for her at all. When me and my boyfriend broke up she wasn’t there to listen. All she would tell me was that he was just a boy and thats how boys are and she wouldn’t even try to help me get over him at all. So yes I am angry at her and I don’t know how to act. What do I do how do I act?
