Try to arrange a date, bring both of them out for dinner over
the wkends. Or ask ur gf to come over ur hse for dinner. Bcuz
during dinner time, its the best opportunity for them to strike up
a common topic. But u have to be the 1 who starts the ball rolling,
so tat both of them dun feel awkward.
It take time for pple to get along. Esp in laws. Like my bf's mum,
she's a headache for us.. but life still have to go on. Mayb u cud
call ur mum once in a blue moon, asking her if she had eaten or
watever, at least show some concern.. dun let her feel neglected.
As for ur dad, u can only protect ur mum and be supportive. I mean
he is ur dad, now he is and forever he is, this is the fact u can't
change. no matter how much hatred u bore, u have to live wif
it.
