Here's the thing: I love my friend but sometimes she's really rude and mean to me. Like today, she smacked my leg (just messing around) and i noticed a red mark and laughed and pointed it out she told me to stop crying about it, and i really don't see how i was. The thing that really makes me mad though is that if i use some comeback like her she gets mad and won't talk to me when i ALWAYS forgive her in like ten minuets. If i talk to her, she deny's it. I'm sick of it. The problem is we're really close and if i start talking to her less she'll notice and confront me and i'm not ready to NOT be friends with her i have no idea what to do :/

Your decision to forgive her so quickly is your decision - remember that! Just because you're so lenient with her doesn't mean she will be with you, which might make you rethink how easy you've been on her lately. She thinks hitting you and teasing you is funny but, for you, it's totally not. Instead of forgiving, forgetting, and keeping it all inside, you need to talk to her and make her hear how you're feeling, however much she tries to deny it. Tell her you know she probably just thinks she's joking around, and you love how fun and light-hearted she is, but sometimes it goes too far. Just tell her maybe your humor is a little different than hers so you're kind of hurt by some of the stuff she does. Tell her you love her as a friend (this really helps make her feel like you're not attacking her) and you just want to be honest so you can continue having a fun and happy time together!
