Alright guys,

so me and the ex who I was madly in love with and was the best fuck of my life split up about a month ago while i was working in the UAE.
the other day she practically begged me to talk to her so i let her stew a little bit and then we SPAM and she asked if she can see me when im back un the UK tomorrow..eventually i agreed.
She said she would book a hotel etc and that she wants to sleep with me again as "it's incredible" blah blah so i agreed.

anyway i messaged her last night to check the hotel situation and she said why should she bother as i've been a dick head to her and talking to her like shit!

now i'm a little confused here, it seems like when i give her no attention then she comes crawling but as soon as i give her the slightest she says im treating her like shit. she's been sleeping around alot since we broke up - i know this because she's told me etc and keeps asking if i've slept with anyone else..she asks about this girl i've known for years who my ex knows really likes me so naturally my ex hates her.

Anyway my question if anyone can answer it is why the hell does she always talk to me about sex with me, asks when she can see me etc then all of a sudden turns psycho? it makes me feel really shit as she totally ignores me when i communicate etc...what should i do, ignore her completely? or go and meet her and fuck her and just leave after.
the girl is a huge mess since we broke up according to her friends and family, she has completelty changed...we were going to live together etc and she wanted a serious future with me.

I should probably add that my job...i'm surrounded by women pretty much all day at work - believe it or not its annoying at times and i've fucked a few of them (dont tell my ex). - one of the reasons why it ended according to me ex is that she couldn't handle me being with all these women - who might i add are hot! well probably 80% of them are.
I'll admit my confidence is totally knocked from this break up and from my ex fiancé before her. but im at the point i want to delete them both from my mind and just start gaming and seeing as many girls as possible, not looking for a wife etc just take each day as it comes..
one last thing...the ex wants to know when i'm moving back to the UK..as she knows that in June i'll find out if i'm on my pilot scholarship course or not which is going to bring in nearly 100k a year..assuming i pass.

anyway guys sorry for the long rant my head is just up my arse at the minute so any advice good or bad or if you want to tell me to man the fuck up then go ahead! cheers!
