Coming from experiences. Firstly, don't believe anything a woman says, believe her actions. Kapag sinabi nya wala yon, wag ka maniwala, you better observe the situation and her actions and reactions. If she respects you and your relationship, sya na mismo gagawa ng paraan para ideny yung nanliligaw in her own way. Umiwas man, pabaling or directly. If she does nothing, then that is a red flag. That means at the very least she likes the attention she is getting. Now that you've understand the situation, it is now time to act or not. If you know na sya mismo ang gumagawa ng paraan para iwasan ung guy pero tuloy tuloy pa din ung guy, you should confront the guy in a calm assertive dominant manner. Be ready for a physical confrontation at all times but don't let your emotions get to you. If your gf did nothing, I guarantee you there is at least something happening. Tingnan mo circle of friends nya malamang ganun ang kultura nila. Now you decide if you want more anxiety and heartache in the future. Don't ever let your selos get the better of you. Be like Jack. Jack Roberto 😂. Wala nang mas nakakaturn off sa selosong lalake. It signals you are insecure and unable to control your emotions.
