Exactly. If want to stay together then
MUST DO IT. When a person decided to cohabitate with furture partner, must be mentally prepared to do it. Already staying together better find out everything about the him/her. Maybe one of them
CANNOT DO IT how? Assuming everything is good, get married and end up with divorce.
And it is impossible to stay together and just HOLD HAND everyday in the same room and bed. Can't imagine that.
It's like wanting to test drive a car but didn't even start the engine. How to tell if the car can perform or not?
BUT BUT BUT don't do this countless time hor. Only try out if you think you want to marry him/her. If everyone also must stay togther for 1 to 2 yrs, you need 100 years to try out 50 persons.
