I’m breaking 😞

Me and my partner decided to TTC, I already have a son from a previous relationship. We know it’s going to be a long process for us due to medical reasons which I won’t go Into. However my partner is so good with my little boy. My boy calls him daddy a lot of the time, he’s naturally became like his dad they’re so good together. I get incredibly broody sometimes it hurts so bad I just want us to experience having our own baby together. My partner is so good with other children! I always look at his hands imagining him stroking our lil baby’s head! It’s never off my mind. He’s worried too that he won’t be able to produce. I get so broody it really hurts 😞 I don’t know why I’ve posted this but I’m crying
