Frustrated . Long rant

Guys . So I have a 5 month old. And my fiance always has his family over and we go to his family's house.

We leave him with both his dad's house and mom's house for a couple of hours.

My grandma came to visit from LA and I wanted to go visit. I have an orientation tomorrow that would take 1 hour. I told my fiance that I wanted to go and leave my baby with my grandma at my moms house while I go and then visit with them. He said, dont do that. I don't feel comfortable with that. The reason why he says that is because my moms house isn't as nice as his parents home. But my mom cleans and my grandma would never do anything to hurt him. He said he'd rather have my grandmas at our house. But we live far. So I'd have to make one trip. Anyways. I just wanted to vent .
