People do desperate things when they are under a lot of stress…Guys unfortunately usually cheat on their girlfriends. Who knows why….but it’s not because of anything you did. It sounds to me like he was afraid of responsibility, afraid of the idea that moving in together would mean more work for him. It was selfish and stupid, and frankly….you may not want to hear this, but that girl who he cheated with did you a favor by causing the break-up. You deserve someone so much better who can provide for you and take care of you, not cause so much pressure and tension in your life. You deserve a man who will love you and adore you and who will inspire you to do great things, not bring you down. Never doubt that you deserve better than him. That girl may be your worst enemy right now, but when you meet the real guy of your dreams….man will you be thanking her… There are guys out there who will give you so much more than that man did.

Pining is ok, but don’t let this ruin your life. You’re a sexy, youthful woman who has a desire for life. You can’t give up now after fighting for so long. You need to get out there, make some friends, learn what gives you the greatest happiness, and pursue it with no regrets. Pick yourself up and run towards joy.. don’t wallow in sadness. You’ll regret never moving on from this relationship! You have so much in store for you and you can’t let this upset the rest of your life. Prove that woman wrong and don’t let her ruin your life, and prove him wrong by not letting him thing he was the best thing you could have. You deserve so much better, and now it’s time to go after it. Don’t dwell on the past. Live in the present, accept the past, and move toward the future. You have a great life ahead of you, it’s just a matter of taking it into your hands and pushing the "on" button.

Do what makes you happy, find friends that encourage and promote your happiness, and someday soon you’ll run into the guy you’ve needed this whole time…and you’ll be so happy that you got out of this whole mess while you could.

Distract yourself by redecorating the house, or putting in extra hours at work. Take a dance or yoga class, or an art class. Learn an instrument. Take that free time you have now that you don’t have that man to worry about and put it to good use!! Don’t waste it wishing it all had never happened.

And never forget that you are a beautiful, strong woman who has the ability and courage to get through this whole thing and move on to a better, far more fulfilling life.

Best of luck and I hope I helped just a little. You rock, and you better believe it.

EDIT: And keep in mind that taking classes or doing social things to distract yourself will help you meet new people! Nothing like a new friend to keep you busy
