I want to end my relationship because of my girlfriends mom
How is your girlfriend's mom coming between your relationship?
She always disagrees with me about my activities. She hinders our relationship
You should talk about this with your partner. It would be a shame for your relationship to end because of something outside of you and her.
It's okay, I'm tired of her mom.
I'm sorry this is happening to you. I think if you want to end your relationship, you need to talk this through with your girlfriend. Maybe she might be able to talk to her mom so she doesn't interfere as much.
