Scared?

Hi! I’ve been with my fiancé for about 2 years and have had 2 miscarriages. I already have a 5 year old with someone else but he has taken her in as his own ❤️ I’m just looking for someone to rant to lol. I’m afraid he doesn’t want to try anymore for his own kid since we had the miscarriages. I know I’m ready for another one but every time I bring it up he just shrugs it off like he doesn’t want to talk about it or he makes comments like “it’s not going to happen” and then he’ll turn around and say he’s just kidding. Im afraid he’s being serious about it. I just at a loss on what to do 😭
