he just said she wasn't the right person and they had not much in common
So why didn't her tell her this, so she could leave in good time and find someone else?
He stayed with her for years, yet he says they had nothing in common and in the end she had to end it. If they had nothing in common, why didn't he end it himself?
He has always been against marriage, but he told you he wanted marriage and even the kind of place he wanted to get married. He also said he wanted kids but he didn't really.
He lies, because neither you or the Ex would have stayed with him, if he said he didn't want marriage and kids from the beginning.
I'm sorry if you can't see that dishonesty and deception in him. It's also very selfish of him.
Of course he's chilled now, because you don't work with all the men and have limited interaction while you're trying to set up your own business.
You had to push and press for a family.
What he does, is get women and hope he can string them along till it's too late to have kids.
Happened to the Ex and almost happened to you. Don't you see the pattern?
He's not a great guy, but you have a child and are going have to deal with him for many years...even if you split up.
