He doesn’t want to try anymore...

He said it during a fight and confirmed when we’d cooled down. It was his idea, in the first place. I’d been clear given my past relationships/fertility issues I couldn’t do it if it was going to be taken lightly... and here we are. He changed his mind after 6 months. Sometimes I’m completely devastated, sometimes I don’t feel anything at all and I don’t know which is worse. Twenty or so years TTC/worrying... I’m the healthiest I’ve been with the best chances given my age and issues.... I’m so very lost...
