TheFlyingMan,
Some very good advice from these guys. I think when people pin so much on a relationship, its reasonable to expect them to be cut up about it.
When you realise that a relationship with one person is not 100% of your life. Your friends, family, career, success, experiences etc etc. all play a large part in your happiness.. Once you are truly happy with yourself, then you act in a very different way with women. It all starts to come together and you realise THEY re lucky to be with YOU and they are just a small part of your life which won't be nothing without them.
I remember before I made the decision to split with my girlffriend I hung in for a couple of years not happy. Why? because I did not think I could ever find that companionship again. What caused me to finally make the decision to leave was meeting someone else who made me feel happier. I finally realised there was at least one, and lets face it probably thousands of other girls out there that could make me much happier.
So my advice would be don't put so much emphasis on the relationship and do everything you can to ensure you have a busy and fun life and that you are the person YOU want to be.
I also believe that if you do have some issues with sensitivity they are easily solved by using NLP or even going to see an NLP coach or a hypnotherapist. Most it will be your internal state, the questions you ask yourself. I think it would be pretty easy to make a big shift in how you feel, quite quickly.
Anyway, thats my 2 cents
