Should I stop contact with this girl?

The other day a girl commented on my status on Facebook. She said have fun and I replied thanks. She then said " Your welcome.. you should hit me up." My girlfriend saw that status because she liked it. Some time later, my girlfriend was talking to me and suddenly she mentioned that girl and said she doesn't like her and things like that and said that she like to flirt with guys. That girl and my girlfriend go to the same church. My girl never said that she doesn't want me to talk with her anymore or anything like that and I honestly don't think that the girl is just being friendly and is not interested in me like that. But I don't feel right talking with her now since my girl said that but at the same time I don't like ignoring anyone. What do you think, would it be disrespecful to my girl if I keep talking to that girl?
