Am I Overeating? I found out my mom has been sexting my babydaddy

So yesterday, I (F25) was studying for my chemistry quiz, and my mom (F49) was trying to help me find a YouTube video to understand the material better. She found one and handed me her phone to watch it.

As I was watching, I noticed a text from my baby daddy (M26). He usually texts my mom when I’m not home to ask about our daughter (4), arrange visits, or talk to her. I didn’t think much of it since my mom had been watching my daughter while I was at school.

It was then that my whole world shattered. I found out that they had been flirting and having inappropriate conversations for several months. She had even sent him explicit photos on multiple occasions.
When we talked about it later, she admitted how it started, how it escalated into something explicit, and assured me that it never went beyond that.

It’s been 24 hours since I found out. I am still in shock. I feel everything and nothing all at once. I’m so fucking hurt, betrayed, disgusted, humiliated—and completely broken. I’m honestly not sure how to cope, how to process, or even how to move forward.

Thank you for reading.

UPDATE: At first, I was really confused about the overeating comments—then I realized autocorrect got me! I've seen most of your comments, and as much as I wish this were some kind of joke or rage bait, this is my actual life.

I am not with my baby daddy and haven’t been for two years. I don’t care what he does or who he’s with—as long as it’s not my mom.

Some of you are wondering why I’m still living with her. To be honest, it’s been out of guilt and obligation. Living in California is expensive, and I didn’t want her to struggle or be alone. It’s not about childcare or money—I’m fully capable of taking care of myself and my daughter. But my mom is very dependent on me, and I didn’t want to abandon her.

As of today, I have an appointment to speak with a professional to start unpacking all the trauma I’ve been carrying, including this. It’s a step toward healing, and I know I deserve that. In addition to that I will be moving out, and have an already found a few places to apply too.

Thank you for all the support, the jokes, and advice from those that have empathy and compassion.
