Dont take any "rejection" in the dating game as some sort of sign that you are not enough or you are doing things 'wrong'. There are no rules to this.
Im not into "hippy nonense" or whatever you want to call it, however, I am a massive believer that we do give off certain vibes or energy that we dont understand.
I believe we attract people through these vibes and when you are happy, married and content more times than not you get attention when you dont need it, on the flip side, when you want it - you cant seem to get it right.
The best chance you have of meeting someone long term is to live for yourself and to draw happiness from within and dont have meeting someone as the "end goal".
Your good enough as you are.
I know for me and others I have spoken to, we are more attracted to the self confident comfortable in their on skin type, rather than someone who you can tell is looking to meet someone.
