“Old classmate suddenly confessed after 6 years… now it’s been 2 months of silence. What was that?”

I got a New Year message from a girl from my school — someone I barely talked to back then. After 5–6 years of no contact, she suddenly wished me Happy New Year and then randomly told me she has a crush on me. I was shocked because we never really spoke, but I replied nicely and said we could figure things out since I was single and inexperienced with dating.

We started talking a lot. Later, when I returned to college, I found out she’s best friends with my friend/roommate’s girlfriend, which made me suspicious. But I still continued talking to her. We planned to meet during the next vacation to see if things could go forward, but when the time came, she just gave excuses.

After that, I slowly lost interest in texting, and she didn’t message either. I was tired of always texting first, so we both stopped. It’s been around two months now with no contact, so I honestly don’t know what to think anymore — it just feels like it faded on its own. Like what to think is as of? Cauz i keep on thinking what tf did just happen in these months. I also didn't even want to ask my friend about it but I am sure enough he would know complete situation. (I am a 22 final yr btech guy with good cgpa of 8.9 and kinda introvert ig as I don't like showing off etc type shit..loves playing sports but am bad at them too🫠) ANY SUGGESTIONS/ADVISE ? What should I do caus the best thing i thought was to make it fade ig..need some suggestions?
