Evil Solutions.
Holy crap, you're in deep sh**, but that's ok, read what I have to say.
Man, this woman is playing you like a flute...so much lies, depression, patheticness, and she's taking you for the ride. I'm telling you right now, there is a God for giving you the will to search her through, and you SHOULD ABSOLUTELY NOT REGRET IT.
Ask yourself, after all this...if the opportunity would present itself, would she cheat on you with her ex? My take: YES
Ask yourself, are you ready to settle down with a train-wreck and live "happily" ever after? MY take: NO
Ask yourself, do you think it's impossible to fall in love with an other woman? My take: NO
Let me answer your own questions now
Is this life? YUP
Does not everyone get the chance to be happy? IT's NOT TOO LATE
Is this normal? NO!!
Can things work out? NO!!
Could she really love me? GOD KNOWS
Could she really ever love me more than him? ASK THE SHRINE!
Can you have a sucessful relationship with someone if you're not their one true love? IF YOU WANT TO DIE SADLY, YES!!
Is there a God? YES!!
Life can suck, and I'm not here just to tell you that, you need help, you need solutions...and one of this magnitude requires you to be pretty extreme. I swear, I would never ever want to be in your position, EVER...you're in for a sad future the way things are going right now, and what I'm going to tell you is something prett much everyone here will hate, including me...Pack up everything, make all the arrangements, cover your tracks and run somewhere your past can't reach. Change State, Country, ID, LEAVE EVERYTHING BEHIND AND START A NEW LIFE! I can't hit myself enough to tell someone to abandon a child, but this woman is walking misery...if you feel ready to settle down with a not-so-good woman and live a not-so-good life, stay, and fill her void...not love, but the need of being needed.
Evil Situations require Evil Solutions, and I consider this one of them...Can you pickup the courage to start over? This woman is inside my 10 top worst type of women...What will you do? I would be too coward-like to run...that child would be very important to me, but marriage? GOD NO!
God bless your child...and GOOD LUCK.
