I m for:
At first i m start from myself, when i love on person, is difficult to think others, because one person only can take all your time. How can you divided your heart to others?
When you really love someone so madly then you will learn ho to loyal to them.
When you still can cheat to them , that's mean have two reason, first because you not really love to them or simply other are your thing to kill time.
When we mad in love to one person is like this world only for both of us. So only the person are interesting and all our focus directly to them, no others.
That only my thoughts especially for myself . When i love someone than i will always try to love him , build love for him. Falling in love is easy than build love. 😊
