I think deep down you know that the relationship you are in right now is not right for you - if you were happy you wouldnt be having these thoughts. The most worrying thing is the fact you are focusing on your ex boyfriend and creating this image whereby he is everything you want. In reality he isnt. If he was then you would be together now! I think you are so unhappy in your current relationship that you may be creating this idea of a perfect boyfriend with your ex - 6 months is a very short time to know, love and understand someone completely although its the perfect amount of time to create an infatuation - take it from me I know! I also understand the frustration of pouring your heart out to a partner and getting nothing back. In my opinion you should break free of both these relationships and make some time for you to get some clarity in what you want going forward. Happiness is THE most important thing in life and if you dont have that you have nothing. X
