Today my LTR told me about a guy she met in her college (we both are in different colleges) and she kept talking about that guy she said these things about him

"He's taller than you"

"He is different than my other colleagues"

"I liked the way he talked"

"He's handsome"

After this she sent me a picture of that guy and asked me what do I think of him

I said idk and simply said "I'm not liking this" to which she said "I was just doing this to make you jealous as you never show any jealousy when I tell you about other guys and that makes me feel that you don't care" I didn't said anything and told her that I've assignments to do and I've to go what should I do next?

Ps: I can't next her as I don't have any female interaction right now because of online classes
