To all the baby mamas out there who have created some drama...

So what is it about being the baby mama, the ex, and ur man has moved on and is happy with another woman, what is it about the situation that makes you mad or upset? I’m not trying to put the baby mamas down at all, I’m just trying to get your perspective and understand. Is it because you think the new girl is prettier than you and it makes you jealous? Is it because he no longer gives you attention? Be brutally honest! Would like to hear seem deep down honest answers to understand this side of things. I can imagine it would be hard. I am hoping to hear from actual women in this position
