Why did this older woman here block me just because I was talking about my crush? Is it jealousy from her?

I messaged this woman on here who is in the 46-50 age range. Turns out she is an Indian too and I am one too living in Bangalore in India. I am 23 so she is twice my age or maybe even more as she is 46+. As usual, i started talking about my crush Akankshya from University where we are both pursuing MBA and she is also within 21-23 age range and that i hugged her over a week ago and also about her awkward smile. Then she replied that I made her uncomfortable by randomly hugging her and i should find ways to impress her. Then i said it was a goodbye hug from me as it was our last exam and we won't meet for 3 months as our next semester classes will start from August so i am already missing her. Then she said "okay just j*rk off while thinking about her whenever you miss her". Then i replied that i actually called her on the phone a few days ago and had a normal conversation with her on phone. Then i saw she blocked me. Why did she block me just because i was talking about my crush? Is it her jealousy?
