You asked how can I make this guy realize his mistake??
After 91/2 years with mine to the point of accepting his proposal he let me down again on the very point I asked to from the very beginning.
He keeps taking the temper tantrum and not discusing things and walking out and walking back into my life. Now today I made my decision no more come back. He broke the rules he walked out because he could not cope with my demands on him, and demands they became as year after year repeat bad behaviour kept coming back on the scene from his adult children and he kept accepting this.
He did not want to control this and I have said no more.
He wants back but I have said no.
If this is how your partner feels no then you cant do anything about it.
Its hard but obviously he does not feel he wants to commit.
I now have to shake myself off get rid of the what if and what could I have done to change.
I cannot change him if he does not
a. see the need to change
b. does not want to change
c. does not love the person enough to try to discuss what changes prepared to make
Love is hard and makes you either angry, depressed, fearful of the next
Wipe off get on and enjoy your life. Do the things you want to do.
Go to the cinema watch the movie you've always wanted to see and meet your friends have a laugh a cry and whatever. Join something new do something you have not done before.
Get on with enjoying your life.
