When she is "in love" with another guy :-)

So, what do you do when you want to game a chick who is "in love" with another guy (who has jilted her) and she WON'T SHUT UP about it, making you her girlfreind / emotional tampon?

Let's call them HB9 and HB8

I've been hanging out a lot with HB8 (see the "Am I FAT?" thread) and building comfort. She calls me constantly to chat etc, but playfully resists my escalation attempts.
HB9 on the other hand has been a long, slow burn. We get together occasionally and see movies, or go out. She to resists escalation, but not as aggressively. I’ve gotten a bit further with her, but not much.
I’ve been trying to set up a date for Saturday. HB8 wanted to come, but had child care issues, so I invited HB9.
To game HB8, I told her that I had a long talk with HB9, and that I thought I was in love with HB9 now! (kinda true…but it’s more of an infatuation/oneits at this point) I told her that I invited HB9 to the event, but that I hadn’t heard back from her yet.
Basically, I reversed the “I’m in love” frame on her. We went out, and I spent all afternoon carping about HB9 and how special she is to me to HB8. (just like the HBs do to me)
Guess what?
HB8 made arrangements for her kid and is going to the event Saturday, and taking me to a party afterwards.
I’m thinking that the same tactic might work on HB9…..
Oh, and I’m using both of the above HBs as pivots for ANOTHER HB9 at the event.
The reason I think this tactic works is that HB8 feels like she might lose my attention and companionship with HB9 on the scene. It also indirectly demonstrates to her how annoying it is to have someone carping about being “in love” around you.

An update on HB8 (Aviator) and HB9 (Ferrari) and how the sarges are progressing:
Aviator and I have been spending a lot of time together - She helped me shop for clothes Saturday and Sunday, and went for a long walk with me yesterday, again escalating physical contact - before she would only hold hands with me, now she places her arm around my waist when we walk. When I kiss her goodbye, I only get the cheek, so I've started kissing that slowly and softly...
She's still a pivot, but a really good one! She calls herself my "girlfriend enabler" at this point and says she's gonna help me sarge Ferrari. I really dig Aviator, and will continue to build comfort with her.
Here is where it gets interesting:
I saw Ferrari today and figured what the hell, and told her "I'm in love" now with Aviator, but that Aviator has a broken heart, and is resistant to my advances.
:D
The result? - Ferrari called me about 15 minutes later and left a message apologizing for a little shit test she threw at me, and saying she wanted to help me sarge Aviator now! Understand that this is the first time Ferrari has EVER initiated contact with me, or offered to do anything for me.
Well, since this tactic seemed to be working so well, I called Aviator and told her that Ferrari want's to help me sarge HER. She laughed at this, but I can tell this got her attention. She also called later and apologized for throwing a shit test at me.
So here is the deal - each HB is supposedly trying to help me sarge the other HB, and they both know about each other's plans.
Aviator says to ignore Ferrari's invitation, but I think Aviator now has a bit of an axe to grind with Ferrari.
I'm thinking about calling Ferrari back tomorrow and taking her up on her offer - after all, I'm more interested in Aviator anyway at this point.
