HOW???!

How can i NOT get moody or distant (bitchy mood) with my hubby when i see something from his daughter ๐Ÿ˜’ i try not to get uncomfortable or mad or anything like that. But just by simply seeing something that is hers... i just get moody for the rest of the day. I dont wanna get like this every time i do. Soooooooo.....any advice here on how to not let that get to me?
