Is it normal my gf left because she said i am not ready for marriage

Your 25...do not get married. DO NOT have kids.

Study, build your career..

Thank me in 20 yrs.

She sounds pretty desperate to me.
Why does she require you to have a good job, does she need a man to stand for the entire income, can't she work herself or something?
You should do as you feel, if you think she's worth it then give it a try. If you don't feel ready to get married that soon though you shouldn't feel pressured to do so. If she broke up with you for those reasons only, and wasn't prepared to wait, then she can't really feel much for you. Sounds like she only wants the marriage and a man with a nice income and that she wants it now.
And she wanted to get married when you'd only dated for less than 6 months... That's alarming.

I think if you were in love she should have stayed with you, or not dated you in the first place if she had so many boxes to tick. Going back to her may make her lose respect, so if you get a better job, you should do it for yourself, even if you miss her

I don't care for this chick's one track mind.

I agree with momgetthecamera. Have more respect for yourself, don't just get a better job to get her back. Get a better job for YOU. It sounds as though that was an excuse on her part anyway. If she really was in love with you, the job wouldn't matter. You need to start meeting new girls and move on with your life.

Improving your financial situation is a great idea, but don't do it for her. Fuck her. Do it for yourself and then find someone more deserving of your love.

Nope. Be done with her.

This is a common gold digger tactic. Making you worried about losing her, sets you up for manipulation. Now that she is gone, don't talk to her ever again.

Gotta have a good paying job man

Its a good idea, but its not gonna get her back.

I suggest you worry mainly about yourself and your career. If she truly loves you she will wait, and be there for you threw thick and thin

Love your life, become successful in your job and be happy.

Don't trust gold diggers, all they want is money. Believe me, it's not worth marrying someone that only wants you for the money.

Meh. I'm the same way as her. I don't see the point of dating if marriage and family isn't part of the plan. But that's something that both of y'all would need to agree upon together.
