HAMMSTERATTACK:
First of all, younger women probably like you just as much, it's simply that older women are more confident in expressing their desires, surprisingly they can be very experitmental and impressivly self assured when it comes to flirting with people they like.
Call her up, agree to meet for something light, like a grab a drink, nothing to pressured, my guess is with the age difference she is looking for a one night stand.
Get her out with you, and escalate things, she'll be quite happy to go along with it seeing as she seems to have done alot of escalating so far

.
Really, this is the point where all I can say is, if you want it, GO DO IT! good luck man
CAPTAIN AWESOME:
QUICK! I NEED A BAND AID!
I don't like handing out one liners, so I'll give you a check list instead.
I want you to think this over and see if you can get a answer for yourself.. if not then ask again.
The next time this happens, once it is over ask yourself this.
-What is his motive for being an AMOG?
- Is it affecting how you percieve yourself?
-Is it affecting the girls perception of you?
-Does it matter if he tries to be a dick?
-Is he stopping after being AMOGed back?
-Are you going to have to pacify him instead?
-How can you use his motive to pacify him?
EDIT: Incidently, you could try kicking him in the shins... or climbing stairs..... I hear their is an alpha male patrolling schools in england, he has particularly weak legs, not much is known apart from that, and he has an affinity for basketball.....................................
