Debs,
First of all let me make this clear this is just my opinion and is free, so take it for what you paid for it.
1. Be in male mode when she arrives.
2. Sit down with her and ask why all of a sudden she is OK with your dressing.
3. Find out why she does not want sex with you. Be careful here word it nicely.
4. Be calm and civil at all times with her.
5. Do not make accusations or throw dispersions her way.
6. Take her out to dinner and show her a good time.
If after all of this she does not give you all of the answers beware of Trogens bearing gifts.
Best of luck,
Fran
