Maybe she just doesnt know what to say although she has had a m/c before i have had a child pass away on me when he was a few hours old but i still struggle to condole other people whos children have passed. Or my other theory when she had her m/c maybe she wanted a lot of space just by herself and got bombarded by people and is trying to give you space to reflect. I dont know im just trying to put a positive spin on it and thats my positive thoughts!
