I think Loulou should consider:
Why are we together?
Do you have the same hobbies?
Whether the personality is appropriate.
Whether the family is suitable.
Do you love her?
Above, you don't have to look at the first four. If you don't love it, divide it. Good for everyone.
Long-term lifestyles are different and there is no common interest. Do you want to do this all the time?
