@SteMan,
Steman,
You know "chemistry" can be an amazing thing but it sometimes stops there.
She wanted you to change, have ambition, make "money", and so you now have two jobs, and school.. Have you not made the change that she wanted?
She loved with you, now going to her Dad's.. You let her use your car, let her have male friends, let her stay with you whilst broken up but allow her to have sex with you because she is horny, let her eat your food, probably use your electricity, water, pays nothing right?
I know at 27 it would be great to find your dream girl. But, don't you want one that pays her way, that doesn't keep putting you down, or using your money, petrol, wear and tear, and the house, everything?
Don't you see that the second job, is not about ambition to her, it's about how much money she can spend. She is high maintenance, she is self obsorbed.
You could find a million women like this that will reel you in and let you go as long as you give, and obviously you are good in bed:)
Is this what you really want? Or can you look at yourself in that mirror and say I deserve better, actually.
