Being cheated on and lied to really does hurt. When I was cheated on by a girl and she got pregnant...it left me damaged and unwilling to trust for a very long time but I look at it as a learning curve. One thing I will say is that when you have a "feeling" that bad vibe then go with it and follow your instincts because I know I did and I was able to find out the truth which somewhat helped. Don't rush into serious relationships, hang back and play it safe afterall there is no rush
