Going to leave my Q this week

This weekend my (27f) Q(35m) lied to be about his drinking, this makes at least the 3rd time. I wouldn’t be surprised if he didn’t tell me about him drinking when he said he wasn’t more than that though. I am so nervous. I am so exhausted in this relationship, but I am a chronic people pleaser and I’m so afraid I’m just going to cave and stay. Again. We have been together for about 8-9 months and he hid the severity of his drinking (and weed) problem from me until about 3 months in. I should have left then but I thought I could help, I thought we wanted to be better. He’s clearly not ready to quit yet, but I am ready to move on. I can’t keep doing this. I have to take care of myself. This isn’t a future I want for myself.
