I am a 21 year- old ambitious girl, with dreams of becoming successful in my career. I am dating this amazing guy who is perfect for me, and I am aware that this is as good as it gets and that I will never find someone who will make me as happy as he does. But I am afraid I fear commitments. I don't know when it all started and how, but I guess it has something to do with people around me. I am surrounded with girls who were betrayed, hurt, divorced, no matter how long they stayed together or how deeply in love they were. They all say the same thing at the end – " He turned out to be someone else after marriage." I know I want to have kids someday and start a family with the person I love, but I am afraid that even if I am head over heels for him right now, it will all fade away later on. I don’t want to scare him away, so I try not to show it. But I am a very sensitive person and I am not so good at hiding how I feel. What do I do?
