We've already been together for 6 months before my partner had to go back to the home country to help his family. Those 6 months are the most exciting, fun-filled and happiest moments of my life. That's why I'm really trying my best to figure out how long distance relationships work.
Yes...it is always wonderful at the beginning

I don't want to rain on your parade; but, sometimes, you can be with someone for years and be shocked by what you discover. Especially if you haven't been immunized against blind love. And, by the looks of it, you haven't
And when someone is far, it is much easier for them to hide their bad sides, or for you to overlook red flags.
Basically, normal relationships are risky and difficult as is. Distance will only multiply the risks and difficulty.
Unless, as I said, the distance is for a short, pre-determined time. Never wait for a guy who doesn't give you clear commitments. He will waste your time and string you along while he figures out his life. Remember: men have more time than women.
I suggest you kindly tell him that you don't want to end up having your time wasted, and that he needs to give you reasonable assurances and time frames. If he cares about you, he will understand. If he gets scared and runs, count yourself lucky you did not waste longer on him.
May I ask what the home country is? Do you mean Lebanon?
