Ask yourself why on earth would somebody just pop up back into your life and want to try something if it's been months and years since you guys last talked? Assuming they didn't want to take things slow and get to know you again, who you are today, as opposed to who you were then and just jump into something? Red flags all over the place.
I really want to believe that people do change, I just don't like the feel of this.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
