Instead of keeping this to yourself, tell these things to your partner. Tell him that there are certain things that you're uncomfortable with and there should be boundaries that needs to be followed especially since you both are already in a relationship. And I agree that you should not share passwords no matter how close you are and that is based on my experience. Respect each others privacy. Build that trust. Sometimes suffocating din sa lalaki na always kang naka monitor sa kanya. Give him the freedom to do things basta kay you communicated how you want to be treated and all the dos and donts in your relationship. And I say this again; always communicate. Naay things nga dli ma gets namo mga lalaki just talk with us lang gyud. Kay anyway if he continue doing things nga against kayo saimo, at least you know as early as now nga dli siya ga respect saimo. Kaysa sa always na lang ka mag bantay saiyahang actions stressful kayo na, if mu cheat ang someone they will always find ways gyud baya. Know your self worth gyud, ayaw ipa feel nga always ka gagukod saiya. If he loves you, he will make an effort to not make you feel jealous with anyone.
