She never needed you. She wanted you. You threw her out of your life. Now you get to watch as she finds happiness again.
She went through hell for you--- just to be thrown to the curb. You never knew how much she did for you because you were too blind chasing a good time. That was and still is on you and you alone. The relationship you guys shared is in the past and I hope you remember that as you both go on with your lives.
With that being said, don't expect her to be down and out for months over the break up---that's not how she is. In her mind, if you think you can live without her, then you can, and she can't change it. She's going to find someone who feels he can't live without her. Someone who will treat her like you never did. However, don't you dare go around throwing her under the bus when she does.
Guys can go out and make their rounds, but apparently it's frowned upon when a good girl goes to try and find a new serious relationship. You go out and you find your next good time on Tinder or at the bar while she goes to find a guy worth spending the rest of her life with. At the same time, remember that she wasn't the one to walk away, you were.
Have fun watching her post on Snapchat when he sings at the top of his lungs with her on their date. Have fun seeing him hold her tiny hands like you did. Have fun watching her get treated right. Have fun seeing her smile for real again and knowing that it isn't because of you anymore. I hope you thought about this possibility when you decided she wasn't good enough for you anymore.
I hope you remember not to drunk text her after you realize you were stupid to let a good girl go. I hope you don't come at her and her new relationship. I hope you don't bad talk them, especially her. I hope you come to grips that she isn't going to sit there and beg you to take her back. I hope you realize that she isn't moving on to show off.
Don't you dare try to come back into her life though. Don't play with her emotions like that. You broke her and it's up to her on how she wants to piece herself back together. Please realize all of this. Please accept that she's moving on, whether you like the timing or person or not. Please just leave it be and don't mess this up for her. Please don't play mind games with her.
Let her be her and you be you. Ya'll had a good run until you let her go. Nothing can change that now. I wish you the best and hope you find something permanent one day. I also wish her the best in finding a guy who is ready for permanent.
So here is to you, the ex, as she moves on.
