I don't want to listen to my mum vent about me
What is your mom's reason for venting about you?
It's been a year since I last paid close attention to her.
Instead of ignoring your mother, you should talk to her about why she's upset with you and see if you can find a common ground. You can strengthen your relationship and grow closer together in the process.
It's not like she listened to me or did anything for me. Maybe when I'm in a worse situation she won't even come to me.
Try to let your mother know how you feel so you can become closer. Simply ignoring her is also ignoring the issue, which will keep the issue exactly the same.
