Step mom struggle

I've been in my step daughters life since she was about 8 months old. She will be 6 in 2 weeks. Me and her mother have had exactly 2 encounters infront of my step daughter in all this time. Both time she yelled and screamed at me infront of her daughter how she hates me. I didn't react. I felt sad for our daugther who witnessed this and didn't understand why the 2 people she absolutely loves...fight and avoid eachother.

I've been patient. And waited. The school and teachers include me in mother's day gift, parent teacher nights. Christmas concerts,etc. However BM refuses for me to be there, and uses daughter as pawn. So I do not attend. She will hold daugther from us when she is mad. She will not even acknowledge I exist. " Tell HER to pick our daughter up from daycare, tell HER she can't come, tell HER to dress our daughter in this and do her hair. Tell HER to buy a gift for our daughter bday present. I let slide. For years.

Today. After our daughter was with us for 5 days while my SO was home (dad), we had to drive to airport to drop him off and I was to drop her off at daycare. Mom texted dad daycare is closed, and we asked to meet so she can pick her up cause I'm leaving out of town for the long weekend to my family. Mother refused to pick her up and said "her STEPMOM can take care her, she wants the title so bad, this is my day and I'm not coming to get her." ... I kept her no problem, but thought "your day?" We've had her for 5 days. you've had 5 days to yourself. Kid free. Relax. Recharge. Party. Whatever you wanna do, you've had 5 days. And this is the day you are scheduled to pick her up and have her.

We went to library, mall, played. Blah blah. Daughter was upset and wanted to talk to mom, so I texted her and said ____ is really sad and misses you ,can she call you? No response. At all.

Someone was supposed to meet me at 10am, 1 pm, 3 pm. not mom, but other family members because mom "couldn't".. And nothing happened until 5pm. and I had to drive acroas the city to drop her off. I then had to leave town(opposite side) and drive for hours to get where I was supposed to be. With my 10 months old baby. I was so upset that she demanded and expected I throw all my plans to help her, and she couldn't even respond to her daughter when she needed her reassurance and love. All day I was unsure where I was taking her. Saying everyone is working.and she said why cant I see my mom, I want to go home and see my mom. I felt so heartbroken for her. And So angry with her mom. I get you don't like me. Don't make your child suffer.

Phew... Rant over. Thanks if you read that whole thing 😬🤗😣😁😯😬
