distant partner...

Katie
Hi all, I've had two miscarriages over the last 18months (last one was Feb this year at 10.5 weeks) and over the last couple of months I've noticed my SO is being very distant and won't talk about TTC anymore. Sex is still fun and we don't always use protection but whenever I try to bring up the subject of babies he switches off. Has anyone else experienced this kind of behaviour from their man, if so how did you overcome it?
