I feel guilty for ending an online relationship over their weight after several months of talking and then meeting in person

Basically as what I said I had been talking to somebody online for about 5 months or so. We lived in different countries and it was entirely unintentional on both parts.

We happened to be in the same discord server and clicked extremely well. Honestly, I can’t say anything negative about her as a person. She treated me extremely well in that time, we had some common interests, and I even found myself falling in love with her at one point or another. I said “I love you” embarrassingly early, about a month in.

No person has ever treated me as well as She did which is why this is so conflicting for me.

Anyway, I flew to Thailand last week and once we met in person I realized that she was a bit bigger than I had thought. I’ve seen photos, and I’ve video chatted with her multiple times but she were still a bit different than what I imagined.

Because of this I was no longer physically attracted to her. I spent a few days with her to see if I could get over it and I just couldn’t. I was honest, she didn’t take it well and yeah we haven’t spoken since. I flew home way earlier than planned.

Anyways… should I try reaching out and apologizing? Should I try making it work even? Am I being shallow? Physical attraction is so important in a relationship and I just can’t see what I did as being wrong. Though I will say they are definitely valid in their feelings. So guys, Could I have handled it better?
