am I wrong to date someone who is two years younger than me?

this story took place back when I was in high school, 18, about to graduate. I was in a play for my high school acting class and there was this boy, who was 16 at the time, that everyone thought was odd. we were casted as counterparts, a couple. he hadn’t had his first kiss yet and didn’t want it to be in front of our teacher. so I offered to go to his house and give him his first kiss in private and platonically. (this isn’t the first time someone has does this in our theatre program, so I thought it was okay.) the kiss happened and he said he felt a spark and asked me to be his girlfriend. me being stupid and desperate, I said yes. fast forward a few days, I told my friends and they were all disgusted with me. over the next few days, they proceeded to drop me and word had spread around the school. I had gotten mean dms calling me a pedo and such. I thought I was happy with the boy but a part of me felt disgusted with myself. I was embarrassed to be in public with him since he was a bit…much. after three months of us dating, I broke things off, telling him that we weren’t a good match. we remained friends. as time went by, I realized how wrong I was. I was a senior dating a sophomore and I had lost all my friends because of it.

fast forward to now. i’m 20 and have been dating my new boyfriend for 8 months now and happier then ever. but I still don’t have friends cause I dropped out of college and just got laid off from my job. (on the job hunt currently.) i am no longer friends with the boy because he was acting kinda stalker(ish) towards my boyfriend and I. I did realize that those friends I had back in high school were toxic so i’m honestly glad they are out of my life. but that won’t have happened unless I dated that boy. looking back on it, i’m really grossed out with myself. I regret ever dating him, but at the same time, i’m grateful for it happening because I realized that those friends were bad people.

so,

am I wrong for dating someone who was two years younger than me?

note: the boy and I did not have sex when together.
