i also experienced that... hanggang sa hindi ko na talaga nakayanan at nakipaghiwalay na ako sa asawa ko... actually the story was the same, except sa pagiging lasengga at huweting... but im facing a problem now, she was bothering me now and my children did not accept my calls dahil pinapagalitan nya, before she did not accepting the money i send, but now she was asking too much from my salary, i admit i have someone now but she push me to be in this situation, for many years i been trying to understand and think about our marriage and our family, she never think the way i think about ours. I was once a battered husband... i never told to anyone because it was awkward and i dont want her na mapahiya... and it was the biggest mistake...
you can help your father by reporting/blotter it to the barangay, you may request too na mamagitan sila.
I was hoping that my daughter was like you, unlike mine na nagagamit ng kaniyang ina para magsinungaling at gumawa ng kung ano-anong kwento... which at the first place they are the one who advice me to live separately with their mom.
Help your father. God Bless
