MY PARENTS HAVE NEVER MET MY BF !

Okay so a little back story before i get in the topic...

So I met my now bf when i was a senior in high school and i was 17 and he was 20 and turned 21 like two months after i met him. i still didn’t turn 18 for another 3 months. I met him on Tinder ( yes as a 17 yr old ik i shouldn’t have been on there and no i didn’t have sex with anyone on Tinder just talked to guys.)

Me and my my now bf, at the time texted but never saw eachother bcuz he lived 3 hours away from me. so we didn’t really see each other or anything at all. nor did we have sex while i was 17 (i live in texas and by the romeo and juliet law it is legal even if we did, BUT WE DIDN’T) i lied about my age at first then told him the truth and at the time he respectfully asked if he could talk to my parents bcuz he didn’t want them to think he was trying to take advantage of me or anything bcuz he was already basically 21.

fast forward my parents ended up finding out that we were talking and his age, and they were pissed. (no they didn’t call the police.) so on and off throughout my senior year we would text but never saw each other and never made anything official. nor did we send nudes or anything like that.

when i turned 18, we decided to start dating and now i’m 19 about to turn 20 in two months and he just turned 23. we are still together and now have our own apartment.

the problem is my parents have still never met him and i have met all of his family at this point. my step dad is the ring leader and has always said he will never meet him bcuz of his age i’m assuming (when he’s only 3 years older than me) and all my bf has ever done is taken care of me when i had nowhere to stay and no money and everything he was there and took care of me.

my mom on the other hand i know would meet him (my biological father was 28 and my mom was 16-17 and they were in a consensual relationship so i would think if anyone were to understand it would be my mom) but because my step dad won’t i feel like she won’t. she always asks about him and we openly talk about him all the time. but she has never made the push to meet him and ive been living with him in a city 3 hours away with him since i was 18.

Am i crazy or wrong for thinking my parents are wrong for never meeting somebody so important to me in my life or making an effort to do so? are me and his age gap really that big of deal?

p.s. his parents always knew how old i was and never had an issue with it.

Thoughtssss????
