Should i dm her?

Okay, so I’m attending a group session in my area for people between 18–26 years old. It’s once a month and usually about random topics like emotions and how to talk with people, social skills, etc. I’ve been going there for about 7 months now.

I’m interested in a woman from the group. I don’t know if it’s a full-on crush, but I’d like to get to know her better. We’ve had small talk before, so it’s not like we’re strangers. I was thinking about maybe talking more, getting a bit closer, and eventually asking her out to get to know each other better.

The thing is, she hasn’t been coming to the group sessions for about 2 months. Instagram keeps suggesting her account to me, so I’ve been thinking about maybe DMing her. But I don’t know… it feels a bit wrong. What if she’s not interested and says no when I ask to get to know her better? I also don’t want her to feel uncomfortable coming back to the group sessions because of me. I don’t want to be inconsiderate.

At the same time, we’re adults I’m 25 and she’s 26 so it should be fine, right? I’m not sure if I should wait and see her in real life again or just go for it and send her a DM. My friends say I should just DM her. Really dont know any advice?
