does she like me?

Hi, so there's this girl I've known for around 2 years. I've never really hung out with her much and we barely text or call each other. She lives in the same apartment building as me and she's quite shy. She's not a great texter and struggles to keep a conversation going, so I stopped texting her for a few months.

When I visited Japan, I messaged her to see if she wanted to hang out while she was there, and she agreed. We met up, had fun, and I treated her to dinner while she treated me to some other activities. She mentioned wanting to go to a haunted house, so we went, and she started grabbing my arm. I then grabbed her hand, and we held hands throughout the haunted house before letting go once we were finished.

Now that I'm back home, she's reverted to her poor texting habits. Should I give up on her or keep pursuing her ?
