Broke up with my boyfriend twice my age. AITAH?

I (20F) met my (now ex) boyfriend on tinder when I was 18. We’ll call him Don. He was 37 at the time. We’ve been dating since then, until I broke up with him yesterday, because I met a new guy my age and am super into him. I ignored everyone who told me that the age gap was weird and have kept it a secret from many people. I’ve lied to friends and family about where I’m going every single weekend for 2 years, because I was going to Don’s house. The guilt ate me alive but I was able to keep my secret. Our sex life was making me miserable, though. He was constantly pressuring me and would act angry when I didn’t want to, so I gave in a lot.

I knew it needed to end. I know that it’s my fault for getting into that situation in the first place. I feel bad that I broke up with Don. Did I do the right thing?
