sounds like your girl has entered the jealousy period. women will often refer to this as the "commitment" period - hahaha.
its that point where you've banged them 100 times or so, they know they cant control you anymore purely through sex, and they start to worry about what NEW value you now place on them.
in the face of diminishing interest from you (or rather the FEAR of such) women typically use one of the following strategies...
1) push for clearly defined commitment - ie. this is heading to the marriage alter
2) try to get pregnant - oopps forgot to take the pill
3) start flirting with other guys and setting up their back up in case you lose interest.
4) nag you to death about how you aren't paying them enough attention
prior to inacting one of these options a woman will often first try to put you in a lose lose scenario (which ive talked about many times in various posts). she will do this by clearly articulating a problem and addressing that problem to YOUR behavior. she will attempt to incite anxiety and fear in you that if you dont change you will lose her. this is her attempt at remaining the PRIZE - which she knows gets harder and harder after you've banged her 100+ times and your value of her becomes based on who she is as a person instead of the hole between her legs.
an AFC will break down when put in to the lose lose scenario. they will either become whipped OR will lose their cool. in the prior the AFC can look forward to a life is bullsh*t and nagging. In the latter they enter the drama zone and can look forward to months of arguments and fights, typically ending in their gf leaving htem or cheating on them, followed then by months of wondering why they are such a loser and can't keep a woman.
the only way to turn your situation in to a win win - which is already is provided you handle it right - is to sit down and talk to her like she is a child. tell her that it is clearly evident that she has low self esteem and that she is taking that out on you.
now shes going to argue that its not her - ITS YOU!
to which you have to stay firm. you have to continue to explain that you care about her deeply BUT the level of attention she is requesting simply isn't possible with your work commitments. You would change it if you could, but you can't - so thats that. what she needs to do is take some time to think about what she wants. If what she needs is a partner who can afford to be with her every free moment of every day - then perhaps you need to discuss whether this relationship should continue.
now, she'll probably pull a pouting session and threaten to leave to see if she can break you and have you do things her way. but after that one of three things will happen...
1) she will GROW UP and start placing realistic demands on you OR
2) she will leave you
3) she will grudgingly come back. if she does this odds are she's only back because she cant stand to be alone, and shes only with you until she can find someone else.
if 2 or 3 happen - good riddence. better to get ride of her sooner rather than later. if 1 happens, then theres a chance things will work out for the better.
if shes a LOW quality woman nothing you do will turn her in to a HIGH quality woman. so what you need to know is which is she. your actually giving her a chance to GROW and turn in to a HIGH quality woman - but you can force her to take that path.
if she is set on being a low quality woman and thinking that YOU are the problem, then you need to accept shes low quality and decide whether you are OK with that or whether you want to keep your search going for a HIGH quality woman.
just my 2 cents.
