Hi, I'm new to all this so apologies if it's the wrong place. Three years ago I started seeing a wonderful guy, who was separated from his wife. They have two wonderful children together who over the years, I became really close to. When we first got together he told me he'd had a vasectomy because his relationship became toxic and he didn't want more children with his wife. I understood and accepted that. We had been together about 12 months when HE brought up the subject of children and asked me if i would consider having one, I started thinking about it. We agreed that he would have a reversal.... Now his ex has ended the relationship she was in and has started being a nightmare. She is trying to stop him seeing his girls and is making life difficult. He has now said that he doesn't think he can have more children as we might split up and the same thing will happen. I need some advice. When we got together I understood that children were not an option but he put it out there and I don't know what to do. I've just turned 31 and would now love to be a Mum, but I also want to be with him.
