sis glam21vylet, i feel for you. i think her attitude is plain mean and vile! hindi lang maldita, girl. kapal ng mukha niya for being an ADULTERESS, tapos ganyan pa siya maka-asta! her bragging about being connected to the government and having lots of police connections mean that she's threatening you and blackmailing you so you would mind your own business and stay away from their affair, diba? yun ang intindi ko.
i think in your situation (with the affair and all the power-tripping), it's hard to fight fire with fire. yes, madaling sabihin na gantihan mo at isumbong mo sa legal niyang asawa para magkandaleche-leche buhay nila. but sis, kung ganyan katapang/kakapal ang apog niya to have an affair and do vile things, ano pa kaya ang kaya niyang gawin? i'm thinking of you and your family's safety. for all you know, she can turn into a complete psycho kapag may nangyari na hindi ayon sa gusto or plano niya, diba?! BALUKTOT na ang pag-iisip ng ibang tao ngayon, so be careful. don't meddle with the affair na lang. mabubuking at mabubuking din yan. remember, the truth always finds it's way out! and besides, your uncle is a grown-up. whatever the two of them are doing, your uncle should know better and sort out their situation. IMO lang naman.
now, what you can deal with is her attitude towards you. kung ang uncle mo ay keber at kinukonsinte siya, it means either he's scared to tell her off because she has "connections" (right?), or sadly, he cares more about her than you and your lola and the rest of your family. sorry sis, pero that's how i see it. and kung ganon ang uncle mo, na walang pakialam, it doesn't mean you have to play like he does. HELL, NO! pag di mo nadaan yung babaeng yon sa santong dasalan, ano pa ba ang next? PASPASAN! now you can fight FIRE WITH FIRE (since sinabi mo na rin na wala sa plano mo ang mang-deadma)! dahil malinaw naman na that's how she treats you. she doesn't respect you and that's belittling, sis. kaya tapatan mo. dabog ba? dabog ka rin! irap ba? irap ka rin. hindi ka niya masusumbatan on that aspect coz that's what's she's doing as well. as much as possible gawin mo yun pag kayong dalawa lang nasa room, para kahit magsumbong siya, walang witness. pwera na lang dun sa irap. hehe! but be nice to your uncle.
