Sister,
please do not take this as me belittling you.
The fact that you have to say things like this implies that you don't quite grasp the gravity of your religion.
This life is a test. A short one at that too. We are not meant to be here forever and compared to the hearafter, it is nothing.
By not following Allah's commands, we will most likely end up in hell. Our goal is to worship Allah to the best of our abilities. We should lift our gaze away from the dunya and change our focus onto the akhirah. We are slaves of Allah. Pause and think what that entails.
Worshipping shouldn't be seen as a burden either.
Connect with Allah. Make dua for guidance.
When our mindset is such that we desire Allah's pleasure above all else (as we all
should desire) then asking about a practising partner becomes a moot point. We would not even think to do it. Much like marrying a non-muslim, we wouldn't even consider it.
But the fact that you ask, implies that you don't place due importance to the worship of Allah. So first step sister, should be for you to change your perspective on life such that you wholeheartedly and unreseverdly desire the pleasure of Allah, above all else and secondary to none.
Consquences of not having that desire is hellfire. Somebody that doesn't attach importance to prayer and worship is going to be punished severely. Why would you want to marry somebody who will have that fate? He would most likely drag you down with him.
As for not being able to get married if you make such a demand, then realise that all is in the control and power of Allah. Make sincere dua, place religion above all else and InshaAllah doors will open while you thought it was impossible. Be patient and perservere.
Strive to marry an Allah focused individual that will guide you into to become a better muslim too and ultimately take you to jannah.
Sister, understand that none of the 'goodness' a person can have will avail him in the hearafter if he didn't worship Allah.
The criterion ought to be religion first and foremost (which would automatically imply goodness in a person).
