Most Helpful Girl
This One has Said Plenty to me here, dear, and that Is: He doesn't want to be hooked at the hip anymore in a Real Relationship.
This is Reason of the season with being hot and cold, giving you lame duck excuses because he is getting cold duck feet everytime he pushes a button that he is getting closer to your heart, then has a change of Heart because he is thinking of the Commitment that he once shared with you as two birds of a feather. He is Not Ready nor Raring for it right now.
He wants his cake and Eat it Too with being with you but not having to have you all of the time as a Main dish, only when it is convenient for you to Continue your duties to Serve him well. He feels he can come and go and that you will always be there when he is Missing the Kissing.
This what I call a "Full circle problem pattern" where it Continues and comes back to the same softie spot, where nothing else is going forward, just whatever he Says... Goes.
Move on sweetie, he will never change. He is a fickle pickle who isn't koshore for sure and will only Break your heart into many different pieces and never be there for you when the chips are down.
Good luck. xx
