My husband's habits:
-can live inside the bedroom for a year - as long as there's TV and internet
-refuses to have me as his company in a bar/pub (dahil mapapaaway lang daw siya at baka may mangyari sa akin)
-rarely opens up to me
-loves watching documentaries about educational but weird stuff (serial killers, mental disorders, etc)
-CAN look/browse at the same stuff/topic for a long time, over and over (like he's been looking/staring at bicycles EVERY DAY in the internet for 2 years now, even though he has 6 bicycles already)
-huge ego, machismo (the main reason why he cheated on me last year, tinanggalan ko daw kasi siya ng "balls", I was too controlling)
Weird, diba? except for the EGO part, and I think you know what I mean.
So...may tendency. BUT - he asked for my forgiveness and showed remorse for what he's done (the affair). And he's even changed his attitude. Like now, he's able to share his feelings (on our relationship, his work, sports, etc). He also always asks my opinion on almost everything (even on an item he's buying).
My point is, IMO - we all have tendencies to become one (a sociopath). Magva-vary lang in percentage- from 0 to 100 %. I'm talking about tendency lang, not being one. Each and every one of us has his very own demons (or kasamaan/evil) inside, waiting to be unleashed. How? Depends on the circumstances, your environment, your family, friends-- and most specially, YOURSELF. Unless you are "mentally ill"/"mentally challenged", you CAN control the urge/desire before it overwhelms or overpowers you because you still have intact JUDGMENT and INSIGHT. That's why MARRIAGE is possible and can work in the first place. Imagine two different people co-existing?
Remember, we weren't born perfect. Nobody is.
And unfortunately, IMO, you CANNOT control the way your partner thinks, feels, etc. BUT your behavior and actions somehow CAN.
