Sounds like either you need to find another opener to stack on top of this, or find a DHV story that you could use to branch with. I don't really use this opener because of all the publicity it has gotten in the community but if I was I might do something like this...
Jealous GF Opener and the set hasn't completed hooked.
Stack with Myspace Opener - "Oh that reminds me of just one more thing and I really got to go....My past girlfriend xxxxx met this guy on myspace and they've been talking for a while. Would you date anyone you met on myspace?"
Then you need to bridge into some kind of DHV material that is related. Maybe something like: "That kind of reminds me of the time I lived in a house with 3 women roommates...." You'll need to develop your own DHV story but just try to find something like that to weave in and you'll be fine.
Based on the fact that you were able to continue on with some small talk it sounds like the set hooked but you just need to cut the thread and get a fresh topic in there.
Keep up the good work!
