Tian Long shi bu,
I know you are feeling insecure because of her higher
qualification.
But, you know, no one can predict the future.
You are still young, and still have the potential to be someone
successful.
Just because you have lower qualification now, does not mean you
will be a failure several years down the road.
Your girlfriend sticks with you now because she know you have the
potential to become a better person.
Since she did not give up on you, why are you giving up on yourself
already ???
Let me warn you , and please take heed.......
You better not wallow in self pity.
Because self pity will destroy your self-confidence.
And it WILL also destroy your relationship.
If you want a better future for you and your girlfriend, you better
put in more effort into securing a stable future, and don't neglect
your gf along the way.
You are a very lucky man.
