People need to understand that love does not pay bills. If your partner is working hard for the future of you two then you should support them instead of breaking up with them because "they work".
WHY DON'T Y'ALL TALK TO EACH OTHER FIRST??!
Seriously though, if she just broke up out of the blue without trying to solve this first, she wasn't interested in the relationship anyway.
Two people looking into each other's eyes isn't true love, two people looking in the same direction is. If you don't want the same things and can't agree on what you're willing sacrifice to get there it can't work. Turn that bottom penguin the other way son. She did you a favor. You're on the way up and need a partner who will suppprt you through the tough times to be there and reap the good times. Wish her the best in finding what she's after in life and you go do you. Succeed for you and find someone who sees the value in someone with goals. She wants someone there all the time and you can't be that person. No hard feelings, keep going.
It's a part of being adult, lots of shit need to be handled
