" Is it possible to have a relationship with a girl when u can only spend a day per week with her?" by Isamu
Yes, you can find a girl with a busy lifestyle (Like yours), who will have very little time to dedicate to relationships (Except for maybe one day a week). Where you are going to run into problems though is via management of free time. She may want to spend her free time relaxing from work and away from you, when you would want to spend time with her and vice versa.
If you date people with not as busy lifestyles as yours, then yes you may run into problems of them feeling ignored and as not as high priority as other things in your life (And so they should). So all in all, maybe the best solution for you is to get a pen pal until your busy lifestyle is more or less sorted?
Hope above helps
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
