Making friends and asking for people’s numbers from meetups

I started going out on hikes and bushwalks through the meetup app to make new friends. It took me a lot of courage to attend the first meetup as I have social anxiety. I wanted to give up after the first meetup because of me nervousness but I kept going.

I started to meet the same people and got familiar with some people. In particular, I met this girl again and again. She and I hike for the same reasons and we both like to go with the same host. Therefore, it’s mostly just the 3 of us who hike together. We’ve been going on hikes almost every weekend from the last 2 months. She doesn’t feel like a stranger to me anymore. I already have the host’s number but not hers.
