My (31M) partner (28F) is one of the brightest green flags - why is this not enough?

After my last relationship, I prayed for a gentle soul, and I got her. She has a great career working at finance, sweet and kind. After work, she is either swimming, gardening or reading a book. She is also madly in love with me - but is it bad that I... kinda understand why? I plan all our dates. When she wants to travel, I pay for everything - flights, accommodations, plan itineraries. When she has challenges at work, we fire up her excel models on the monitor and we work through stuff together. She regular leans on me for advice on doing better at her job. When she has worries about finances, I work out numbers with her to assure her. She also has a broken family, and I regularly tell her how my parents would accept her with open arms once we marry On the flip side, I have this feeling of wanting more, but not getting it. I'm a very adventurous person who has lots of hobbies. I've tried many times gently nudging her to pick up a sport that we can do together, even offered to pay - but she always feels like I'm pressuring her. So I've stopped raising it. I've also hinted that I want more quality time and meaningful dates, and if I do plan them we do get them. But when I don't plan anything, our dates end up being... ordering takeout and eating it at her place. For my birthday, she got stressed because she couldn't think of what to buy, so I helped her by not getting new glasses so that she could get them for me. It's been 3 weeks, she still has not initiated a date to get them together. TL;DR - she is unproblematic, we rarely ever fight. She respects me. But she is so passively low maintenance that I don't feel connected, share interests etc. at all. I'm tired of asking for more, but on the flip side, I also feel horribly guilty. If she's great at everything else - why can't I just love her for who she is, instead of trying to change her into someone she's not?
