Friend dilemma

So imminently I will start trying to conceive, and I have a very positive mindset so I am really excited. I am also aware that I am in my 40s and there may be challenges ahead. I have always dreamed of being a mother. My friend has just suffered a miscarriage and I was somewhat rather surprised by her reaction. She told me and a mutual friend over lunch. She was extremely detached and very matter-of-fact, she does already have children and very unsupportive, unemotional husband. When she told me about the miscarriage, I tried to be as supportive as I could be and mindful of the situation. I did not obviously tell her that we are going to start trying soon. I was deeply surprised that some of the things she was saying such as well I have three children already so it’s no big deal, well at our age it isn’t really going to happen and if it does can’t guarantee it will be normal, it’s so hard on the body when you are older. On the one hand I totally understand why she is feeling this way and I want to be there for her. But after an evening of solid indifference and negativity, I just felt drained. I cried when I got back home. Worse our mutual friend who is also TTC suspects she might have faked a miscarriage previously, and thinks she might again because the marriage is on the rocks again. I felt mortified but I listened because our mutual friend was genuinely concerned because children are involved. To be honest I don’t know what to think and at the moment I am trying to stay positive. I want to be supportive because whatever the case our friend is clearly hurting. But at the same time and I feel terrible for saying this I can’t face another totally negative conversation. The last thing I want to here is oh you are in your 40s, you may as well give up hope, because there is none. Any thoughts would be appreciated? Sending good vibes to everyone TTC 😊
