My partner and I started dating when I was 23 and he was 35 and while I don’t think OP is in the right, I really feel like we stretched the bounds of what was ok. I still had a lot of learning the basics of being an adult, and he had to put up with some incredibly immature shit from me. We’ve been together 13 years now so I don’t regret it, but I do cringe and worry when I see others following in my footsteps.
