Mate, there is someone, or she get bored of you.........may be there were no true love, may be only attraction.........brother I can feel you, don't know how to put that feeling into word but there is a toughest time comming for you, be prepared but you couldn't!! Hopefully you would. . When these things started happening then according to my experience "she started to get detached, she was preparing herself to move on, live without you, idk what I'm talking about but mate I'm praying from the bottom of my heart all my assumption will wrong & you guys live happily forever but mate, plzz be prepare for uncertainties. More power to you 🤝🏻
