Is it okay for me to feel upset? 😭

My ex husband & I do 50/50 with our daughter. He had her this week for school & knowing Mother’s Day is this weekend, I knew she did activities for it at school. I asked him if she brought anything home and he said yes, that she did an all about mom worksheet.

But the thing is, she didn’t talk about me. She talked about his wife…granted she’s been in her life for a couple of years now but it really did make me sad. I didn’t say anything to him I just said oh okay. He texts me again and told me he asked her why she did that and she said because she knew she was going back to his house today and that she wouldn’t see me until Sunday. Still, I feel really bad and I don’t know how to shake the feeling off 😕
