I was meant to be staying round at this 28 year old milfs house on Saturday night..

Well she totally ignored my facebook messages and texts (I just asked if it's still on for tonight)..

So I text her this morning saying "Well so much for saturday! x"

She replies: Babes I'm so sorry, me heads been up me arse for past few days with work and stuff, Hows you? X"

Where do I go with this? I'm tempted to bin her off just for messing me about on TWO occasions now.. Do I give her another chance?

Background is, she's my dads mates daughter, and she added me on facebook, joked about not seeing me for ten years then started flirting andI arranged to go round to her house..

you dont have enough comfort with her or she might just be a bored out and out time waster.
Get her number and ahve a chat on the phone with her, have a laugh and show her that your ok.
then dont make any sexual references about meeting up but just say lets have a drink or a coffee.
the idea is for there to be no pressure on the meeting.

you might just be flogging a dead horse but youve nothing to lose

Agreed, meeting at her house when you havn't seen each other for 10 years makes it all very high stakes. Quite likely she liked the idea in the abstract but bottled it on the day - something chicks do a lot.

If she is horny and its horny talk thats getting her to agree to it then you should try and do it there and then!

trust me its fun when you do that-- ive had many a trip in my car at 3am after chatting to a drunk chick on the internet about sex.
rolling up at hers and nailing her a few times and getting back home when the suns coming up
