Fell in love with my really close friend (girl) who is married. I really felt like she was leading me on, but she says I'm only a friend. What to do?

We met 1 year back in grad school. We used to chat almost everyday. The way she was looking at me, I felt like there was something more. Multiple instances - glances (even when she thinks I can't see her), blushing, long eye contact, playing with her hair, deep conversations (nothing sexual coz maybe I was just scared to lose a good friend). I was dropping hints and clues, but she never said anything. I finally picked up the courage to confess before the summer break because I wouldn't be seeing her for a long time. I wanted to meet her but she made me do confess via text. She said she saw me as a friend and was sorry if she unintentionally led me on. I didn't want to be friend zoned, so I decided to end things with her in a nice way and told her I need to stay away. She didn't respond to that message, but we would see each other in school and it was awkward. I didn't text her in 4 months, but she did once with some random stuff as a follow up to something I had asked in a mutual chat group. I didn't respond. As fate would have it we were made to sit together in the class. That day we had a casual chat of how things have been without addressing the main topic. Next class our seats were shuffled and it kinda felt like she was ignoring me. I had to leave early so I left. The third class, she came in really late. We were coincidentally twinning in same colour dress. I decided it's now or never. After the class I asked her if we can speak - she agreed. I told her I might leave by month end and just wanted to know if I hurt her with my confession. She said it was fine - "I'm married, What can we do now" and then switched the topic. In our bus back home I asked her if she told her husband, she said yes. I told her I was giving all the hints - she had doubts but thought it couldn't be true since I knew she was married. While leaving she said see you on class next week. I don't how to take this forward. I still love her. She is going to Germany for intern and husband to US.
