At first i would suggest you close the other posts concerning this topic, because i only answer once;-)
Then I assume with FB you mean Fuck Buddy and you want to turn her into a hoe.
And now you are stuck at 78% approval. Since you have made to this amount i think you and your cock are capable enough to satisfy her. Remains only the amount of cash for the present you should give her for your visit. In this case i would suggest having a little bit more cash at your side (100k should do the job until you reach 100%).
Your level (55) doesn't matter in this case.
Other factors which could hinder your visit are the 30 minutes of shame or not having enough excitement (full!!).
Have fun!
