Vday is tomorrow and I feel heartbroken

I’ve never cared about Vday, never.. but i had also never been with a man for Vday. And tomorrow is the day, the day i usually don’t care about. But I’m already feeling anxious. Not because I miss my ex because I don’t miss him anymore, I just miss how he made me feel (the good times lol). But because I know he’s with someone and he’s most likely going to be with her tomorrow. And she’ll have that romantic experience that I never got to have with him. She might even hear words I didn’t get to hear from him. And as much as I know he’s not a good person for me, it just makes me feel extremely lonely and rejected. I feel like tomorrow is going to be this huge day for me and there’s no way around it. I can’t escape it. 💔💔💔
