I feel so sorry for you, my girl, and i know, firsthand, how this pain feel, it's so real, and so devestating.
It's been 2 weeks for me now, and i still tear up crying, almost everyday, i try to find answers, analyse things, in order, to find out, what i did wrong, to learn from that.
I know, Nothing will bring her back to me, she's decided to leave me, and move on with her life, with her new man.
You are NOT to blame, He, however, decided that he want's out.
The people, who leaves their partners, usually feel no sense of responsability, and they do not realise, the path of destruction, that they leave behind.
Therefore, you are now, to take charge of your own life, and this is not as easy as people think. You must realise, that you do not deserve this, and that you are worthy of something better! and you are!
Finding that motivation everyday, to carry on, and stay positive, and find hope in your heart, that "YOU WILL BE HAPPY AGAIN!", you have to believe this.
I promise you, you will be happy again, and all the tears will be long forgotten, for you deserve better, and you will find better.
I agree with Cgreene21, do things for youself, try and spend time with friends, they will be very considerate.
I have learned a lot in the past 2 weeks, on how to survive through this, as i was so close to taking my own life, and then realised, through the help, from all the precious people on this forum, that my life was worth more, than the person, who broke my heart like this.
Me, and you, as well as so many others on this forum, are still trying to get through this trauma in our lifes, but remember this , "YOU WILL BE HAPPY AGAIN!" trust me, i believe the same, and that is what, gets me through everyday.
