What Should I Do If I Lost The Person I love ?

Talk to her, admit you were wrong even if you dont think you were. But dont let her push you around all the time. She needs to know that you have no feelings for anybody else so tel her that you have no feelings for the girl that was messaging you. I have always said communication is the best tool you can ever have in a relationship beacuse you can fix things easily like that. I never fight with someone without learning something new, think to yourself why you guys fight and talk it out. Point out why you guys are fighting and how you guys can fix it as a couple.
