groupie probs?

this summer I ended up sleeping with one of the guys from 5 Seconds of Summer. it was honestly one of the best nights of my life and we still keep in contact, and plan on meeting up again the next time they're in my city. the only problem is, I've really started to catch feelings which I promised myself I wouldn't do. should I continue to sleep with him/sext him even though I'm getting feelings and know we will never work out?
