<human>: Everyone in this story is 19 years old.

Let's say there are two girls: Abby and Jen.

Abby is a good friend of mine. We have lots of classes together, and we have a similar social circle. I was always sort of interested in her, but didn't want to make it awkward by asking her out, so I never thought much of it. Then one day, I met Jen through Abby, who is her best friend. We hit it off at first and started talking for a while. We even went out a few times, but it was never really official. Just going to the movies once, meeting up a few times (casual, no dates), and lots of texting. Abby and some of our other friends know that Jen and I are kind of "a thing", so they're trying to nudge me into making it official. But, I've been slowly losing interest in Jen, and when I met Abby the other day, I guess it rekindled my interest in her. At this point, I've completely lost interest in Jen.

The question is, do I have a chance with Abby? How should I handle my situation with Jen?

Can you give me a shortened version of the text?
<bot>: A and B are best friends, I like A, B likes me, I've gone out with B a few times because I was interested at first, but now I lost interest. Friends are nudging me to ask B out.
