I’m really desperate for help/advice sorry

I’m really sorry to bother you all but I wanted to ask you question as I’m feeling really anxious right now. 

I went on two dates with a woman in August 2023. She made a point to say she’d be busy as she has to sit exams through her job soon to get a qualification. After the second date her text said “thanks for dinner tonight - honestly next time you have to let me get the bill! It was v good to see you again. Hope you got home okay x”. We texted a bit after and then I didn’t hear from her for several days and I felt anxious so sent a rude text because I thought she was just ghosting. She replied and said “I wasn’t trying to ignore you - I was just genuinely busy this week. But you calling me an arsehole is so uncalled for. And tbh I don’t want to see someone who’s going to call me names so I’d rather just call it a day.” I tried to fix it then, a month later and 2 months later but it ended with her saying “I just don’t see this going anywhere. Good luck with everything.” And she blocked my number and Instagram. 

It’s nearly been 3 years since this happened. I’ve felt anxiety about the situation since the day I messed up and I think about her everyday several times a day. I look at her Instagram private profile on another account sometimes and around 2 months ago from looking at her suggested accounts I saw she was following wedding photographer and bridal makeup people who followed her back. I thought maybe she’s helping out someone close who’s getting married. Today I googled her name and someone who i wasn’t sure if she’s with or is related to her and a Pinterest came up with both their names and they’ve jointly pinned a set of pictures called “proposal ideas” and “wedding stage decorations” - it says these pins were done 2 months ago. I’m 90% certain that’s them but I don’t know

Am I able to manifest her back? I genuinely feel like she’s the perfect person for me and we’re the same ethnicity and religion. But I don’t know if it’s been too long and whether she’s gone. Again, I’m sorry to bother you and thank your for reading
