Lindsey, sweetie - it shows you what type of person your ex, and hes new gf are, i seriously do not think they are your kind of people.
I wish i could tell you to stop mixing with them, but no one can tell you what to do.
You are a better class, and you should be proud of that.
There is so much more i would like to say to you, but i think for now, you have your head full enough, so i am going to just give you a loving hug, and will talk later.
I know it's VERY late/early for you at the moment, have a cup of tea, and go lay down with Layla.
Love ya!
