Forum:Kelly & Liara

I had a romance with Liara in ME1. In ME2 I had the one night stand with Jack. On the shadow broker mission, Liara was not too happy about it. I have read that romances in ME2 effect ME1 romances in ME3. So here are a few questions regarding this.

Does a one night stand with Jack (not the true paramour/romance with Omega 4 cut scene) have a permanent effect on continuing the ME1 romance in ME3?

Will inviting Kelly up for dinner have the same reaction out of Liara in the shadow broker mission?

Does any flirting at all with Kelly result in messing up ME1 paramours/romances in ME3?
