Few weeks ago, guy much smaller then me, tried to AMOG me, i waited for him to make more mistakes so i can show him to stop doing it.

Now, i didn't have spot in library so he asked me to take his number and sent him message at any time to take spot for me if im going to be late that day to.

I felt like "aaaaaawwwwww" he's so nice, like he bought me with that kindness, but on other hand, im like so easy to decieve!

I felt sadness when it's time to stand up for myself, what are my next steps for fixing this?
