So, a little while ago, I met a sweet, cute woman in my social anxiety group. We really get along, and she had asked for my number. I gave her my number, and she texted me the next day. 
We had plans for Sunday last week, but she had to cancel because the weather in our area was very dangerous, though she expressed desire for us to hang out.
We did manage to hang out over the weekend! We went to the science center and had loads of fun. We even squeezed into a photo booth and took pictures together. I was dissapointed when it had to end, but I gave her a hug goodbye.
I'm not used to this, so I don't know how long I was supposed to wait before texting her, but I didn't have to worry, because she texted me back as soon as she got home 
The next day I texted her one of the pictures from the photo booth we took, and commented that she looked pretty cute. (Her response: Thanks
)
Something my friend pointed out as a good sign: Last week she said she couldn't go to group that week because she had a family function. I responded that it was too bad, because I liked it when she's there. We then texted back just a couple more times before the conversation ended (she had the last text, I know I should try to restrain myself and not text *endlessly*. But two hours later, she responded back "I like it when you're there too."
That was not the last text I had sent to her, my friend said that meant she had gone back and reread our texts at least once.
We hung out again the other night, had dinner with a couple from the group. I regret this, because it wasn't an intimate dinner like I had wanted; to her it was just our same SA group at a different venue (because it was the same night we usually go to group, and it was implied that the meeting had just been moved.)
I've been smiling, making eye contact; I just don't know if she is interested in me. My friend originally thought she was, now they maybe she does have an interest but is a bit guarded, or that she might just be trying to make friends.
If I can't date this girl, though, I can't be her friend. I've made that mistake before, of being in a one-way relationship, and it took so much wind out of me. That part of my life is over, and I don't want to deal with that again: the pain, the pining, the foolish hope, etc.
I hope that doesn't make me a jerk, and if she isn't interested, I don't want her to be upset when I stop hanging out with her.
I do want things to work out, though. I just can't tell if shes interested romantically or not. People say to just be blunt and ask outright if there is any attraction, but I don't feel confident doing that. I'm going through allot of turmoil in my life right now. If this works out, it will help me immensely. If it doesn't work out, any stability I had left is gone. I have ALLOT riding on this...
