Hey Michelle! Sorry to hear about your ex. Oh man, I bet that was painful. Damn he's robbin the cradle. I think guys take the easy way out, because 20yr olds will put up with a lot more guy drama than an older wiser gal, but at the same time, a 20yr old can sure dish a lot of drama too. I say it won't last!
Just keep doing what you are doing. You are getting so in shape! Go girl, and congrats on getting those new jeans. I bet that felt great. Don't let him get you down. You're better than that, and you know what they say about the best revenge, it's success. Keep your chin up cutie!
