My mom is using me to take advantage of my dad

My parents aren’t together, they haven’t been since I was little. It’s never really bothered me since my parents have a good relationship, they co parent and help each other out when they can. I live with my mom, and while I keep in contact with my dad and see him as often as I can I feel like our relationship could be closer. Since I live with my mom I have a stronger bond with her that I don’t have with my dad as easily.

My dad never minded giving money to me or my mom, if we ever asked her provided no problem, at first my mom only asked for money occasionally and she was honest when she asked that the money was or partial for her.

But the problem started three months ago, one day my mom asked me to ask my dad for money. I was confused because why couldn’t she ask him herself but I said okay and asked.

No big deal she just needed some cash.

Until she just kept asking for more, over time it was starting to add up, and I was starting get uncomfortable with all of it, it felt like my mom was using him as a bank but it was only every once in a while so it was fine?

It’s gotten out of control my mom has started to impersonate me, she would take my phone and text my dad as me asking him for money. She has been doing it without me knowing, she started deleting the messages and the only way I know this is going on is from history on my phone. In the last month she’s gotten 220 dollars from him, for my school fees, or a day with my friends. I don’t know what to do she gets upset whenever I express my discomfort. And when I asked why she doesn’t ask him herself she says “He asks to many questions.”

My mom doesn’t work but she is in a new relationship and her husband does work.

I just wish she didn’t put me in such an uncomfortable position, I am lying to my dad for her, and I am to scared to speak up because I live with her. I love my mom, I just hate what she’s doing.
