There's a cute person at the deli counter in the grocery store that I go to that gets really flustered whenever we interact. I catch them sneaking glances at me when we're not directly interacting so I think they think I'm cute, too. I think they're adorable and would like to ask them out but I've literally never done that before and have no idea how to go about it without seeming weird. I'm also ND and very socially awkward, please help 
This is how I've been trying to get over this. Until now it's been a ridiculously high bar for me to make myself even the slightest bit vulnerable. The last person I really opened up to was a roommate that I talked to for hours from the first day she moved in. After probably 20 hours of relating stories and having a great time over the first couple of weeks of knowing each other, we were sitting on the couch late one night, there was a pause where we were just looking at each other, and something clicked in my brain and I made a move. It was the first time I'd ever done so. We had a brief FWB phase that never progressed into a relationship but we're still friends to this day. We never fought or anything, just realized we had different expectations. I think she knows more about me than anyone else in my life, lol.
