You're allowed to move on, you guys once had something specials but it didn't work, he didn't make it work, you don't have to move on NOW but in moving on you should try to maybe not FORGIVE him because what he did was terrible but try not to be so angry and frustrated with him and you'll find yourself over him :)
Just know that it will get better, it doesn't seem like it now because you're still healing. Try your best not to dwell on him or what he did to you. Good luck, I'm sorry you're having to go through this, unfortunately, it's a part of life.
Take one small step then a bigger one then a bigger one then a bigger one then a bigger one then a bigger one then a bigger one then a bigger one then a bigger one then a bigger one then start to jog then start to jogthen start to jog faster and then faster faster and then faster faster and then faster faster and then faster faster and then faster faster and then faster faster and then faster then run ...FAST SO fast your legs hurt then run more and more run more and morerun more and more run more and more run more and more then sprint as fast as you can. By then you should have moved on :)
That sucks. I've been in the exact same situation - almost the exact same day, in fact, just several years ago. Just remember his actions were immature so it's not worth stressing over. If you're upset that the relationship is over, just remember that it's better that you found out now.
Go to new places and remember the good experiences you shared and think about the things that you learned or were given because of this relationship. Remember that not everybody is a cheater, so don't be afraid to go out and meet new people, and try new things. You will be able to move on after this. You couldn't possibly die from it. Nothing was really lost if you think about it, except him losing you and your trust, and you losing a bit of trust for new people. But what is most important is that that scumbag now knows that he lost a wonderful girlfriend, and that losing you will have made his life miserable. Good luck Sweetie! :)
I am sorry for your sadness. But be thankful you didn't marry him & have his children to find out all this later. Play yourself some kick butt, empowering songs & turn it up... belt it out, even if you make up words. Just purge some of the emotion built up, & try to deal with the rest. But don't turn towards alcohol or drugs, it's not a healthy way to cope. Your problems will just sit there & wait til you pay attention & deal with them. Again I am sorry for what you are going through. He did this, not "to you" but against fidelity... ok? Do not own this as your fault - EVER. Happiness is waiting for you, I promise.
I was in the same situation with my boyfriend and I really loved him but the only way you can move on is too forget about when y'all dated and date someone else put him in the past and put someone new in the future
Cope? Don't let the bitterness towards him get you down, pick yourself up, brush yourself off, and find you someone who is deserving of your love and all you have to offer, mister right is out there, don't just settle, your too good for that. You rock girl, never look back, happy days are ahead!!!!
Put one foot in front of the other... And soon you'll be walking around the floor! Just put one foot in front of the other... And then you'll be walking out the door!!! You've just gotta pick yourself up and keep on moving otherwise you'll miss out on life because of one mistake.
I like M-squared's answer, but I would add that it's OKAY to be sad! The same thing happened to me 2 months after we moved in together, then I had to move back home with my parents! (I was 23) For a month I was angry, I cried and cried, I lost 10 lbs, and looked awful. But then I decided I couldn't stay at home forever, and found my own apt... My friends rallied around, and life got better. We made plans to camp out at the Phila. Folk Festival, and that's when I connected with a guy I had previously met, but didn't really KNOW. We've been married now for 34 years! SO! Take time to grieve over this loss, take the reins of your own life, and enjoy your friends!
