Anyone else constantly made to feel like their feelings don’t matter?

I’m not sure if this is even a 12H thing or what but I figured if anyone may understand it would be y’all. It’s been a pattern I’ve noticed throughout my life, mostly from family members and romantic relationships. Thankfully I have loving and validating friendships or this would be too much. I just had my heartbroken again from someone who I genuinely thought cared for me and about my feelings then proved me completely wrong in the end. When I express my feelings about the situation (calmly and succinctly, mind you) it’s like they don’t even want to hear it. Like yeah yeah just get over it, okay? Or “yeah sorry but”… wtf, man? It’s like my feelings are a package with a sticker that says “fragile” and the mailman just kicks it over the fence, time and time again. I’m sorry if this comes off very “woe is me” but I don’t understand it. I don’t want to be walled off from people, but I just want someone who will treat my feelings with care, the way I do with theirs. But why open up about my deepest feelings and do the hard thing of being vulnerable if I’m just gonna get sh*t on… idk. I don’t even NEED a partner.. would I like one? Ofc. But I love my solitude and my own company. Just leave me alone if you don’t really care, don’t draw me in and make me believe that you do. Ugh! Anyway. Rant over.
