<human>: I have a girlfriend who is wonderful. We've been dating for around a month. I was on snapchat watching peoples' stories and a video came up where my GF's friend had a video where her cleavage/bra is visible for a few seconds and I kept replaying the video trying to see it. I feel so guilty and I'd never leave my GF for this girl. I used to have feelings for this girl but those have long since gone away. I do find her a bit attractive but I don't like her. What do I do? Should I feel guilty?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I watched a snapchat video of a girl I used to have a crush on trying to get a glimpse of her cleavage. I have a GF and now I feel very guilty.
