Relationship Red Flags

My ex and I broke up 7 months ago, and thinking back, I'm noticing red flags that I wish i noticed sooner. The biggest one I remember is when he said "drunk consent shouldnstill count as actual consent. You consent to alcohol, you consent to sex," and I passionately argued with him that social drinks and sexual intercourse are two very different things that shouldn't be related, and he still disagreed with me. What are your relationship red flags?
