I really need advice

Keke

I suffered from a miscarriage 7weeks ago. I haven’t really talked about what happened or how I’m feeling to anyone. But my fiancé keeps touching and rubbing on my belly lately it make me feel weird and I go to thinking about what we lost. How do I approach the conversation to him. He as well haven’t opened up and talked about it either. How do I go about having a conversation with him about our feelings on losing our first child
