My mom doubts my relationships. What should I do?

Hey everyone and happy new year!

So on Christmas Day, I started dating a guy who I will call W. W is one of the sweetest guys I have ever met. He likes me, he’s cute, but most importantly, he respects me and the choices I have made in life. We met on a dating app. My mom HATES dating apps, and HATES that I was on them. She also keeps telling me how he and I didn’t seem affectionate towards each other (I don’t show affection in front of my parents but we cuddled when we were alone), that we started dating kinda fast, we don’t have A LOT of similar interests, and says I should have given some other guy I met a chance. But there was something about W that I liked that made me feel like he was the person I should be with and not the other guy. Also my sister has a boyfriend. My mom never doubts their relationship. And says how sweet he is and he’s a “nice guy” and whatnot, but has always doubted my relationships. Yes I haven’t had the best luck with them but I feel this one is different. And in the end, I’m 22 and who I decide to be with is my choice. So yeah, what should I do about my mom doubting my relationship? Which has increased my anxiety. Thank you!
