Struggling with attraction after ending things, need some advice from married brothers.

Salam everyone. I'm a Muslim guy and I was talking to a woman for marriage in a halal way for about 5 to 6 months. We only met in person once before I decided to end it. Honestly, on paper she's amazing. Her character is solid, her deen is strong, she's kind, respectful, family-focused, and we share the same background, values, and love for Islam. We both care about family, prayer, traveling, and building a good life together. She even has feelings for me. The problem is I'm not physically attracted to her. When we first started talking, I saw older pictures where she looked slimmer, but I realized later they were from years ago. When we met, she's overweight and I just didn't feel that attraction at first. Because of that, I broke it off even though we'd already built a strong emotional connection over those months. Now I'm really torn up about it and keep thinking about all her good qualities. We had a final chat, and she mentioned that the gifts I gave her-a Qur'an and some perfume-made her think of me and she'd cry every time she saw them. I took them back as an amanah and plan to give them to charity. Hearing how much she was hurt made me feel even worse. I'm also upset with myself because I wish I'd met her sooner before we got so close. Maybe then I'd have known about the attraction issue earlier. What's confusing is when I saw her a second time, I thought she looked a bit cuter-not a huge change, but slightly better. Now I can't stop wondering if attraction could grow over time. I think I might love her as a person; she brings me peace and comfort, and I worry I won't find someone like her again. But at the same time, I don't want to marry someone if I'm secretly struggling with attraction. She deserves a husband who truly desires and chooses her, not someone who's just forcing it because her character is good. So my question is: is slight attraction, combined with really strong emotional, religious, and character compatibility, enough to go ahead with marriage? Or is it unfair to continue if the physical attraction is weak? I've decided to pray istikhara and give myself 7 days before letting her know if I want to continue or keep things ended. I'd really appreciate advice from married Muslims, especially brothers, since you might have been in a similar spot. JazakAllah khair.
