With every new relationship, you are the "new guy". If you want to stop being the new guy, then you'll have to stop dating.

I'm amazed that someone with your past has the cheek to criticise anyone else, though...! Take a good look at yourself, and what you bring to the table, and ask what you really have to offer a relationship given your previous experiences. It may be that she's unconsciously looking for someone who is unable to commit - a married man would fit the bill, and so would someone like yourself.

My advice to you is to enjoy your relationship for as long as it lasts, and stop trying to sabotage it! Getting Ready for a First Date
