several thoughts:
has anna and ming broke off "officially"? i think there is a need
to close the loop, especially when it comes to relationships.
what are the reasons why anna's mum likes ming, and wants her to
leave you and go back to him? how much does she know ming, and how
much does she know you?
at this point in time, what is the status of your relationship? has
anna decided once and for all to break up with you and go back to
ming, in accordance to her mum's wishes?
and in all relationships, it takes two hands to clap. there is no
one party who is right or wrong - most of the time. so there is no
point in blaming yourself. love, as in all relationships, involve
not only the 2 parties, but also the persons the 2 are involved in,
because the 2 parties love and are loved by others, albeit in
different forms. it is almost like politics - that of compromise
and middle ground and common interest.
anyway what us outsiders can do are limited. we can only prompt
you, so that things that may not have come to you can become
clearer - dang ju ze mi, naturally. but you will have to find the
answers yourself. in the end, relationships are matters of the
heart. follow your heart, while taking your head's advice, and
sticking to your values and principles. you won't go too far off
this way.
