They don’t deserve to be treated like nothing. They should be respected and treated like a human, not like some sort of object.
If you really love her, then treat her like a princess. Never do anything stupid. Never make her cry. Never ignore her. Never turn your back on her when she needs you to be there for her. If you truly do love her, then why hurt her In the first place?, she’s your girl, you put all this efforts in trying to get her, then why ruin it? You know, while you’re ignoring her, while you’re treating her badly, another guy is looking at her and wishing that she was his. Don’t give him the opportunity to take your place. She gave you her heart, then the only thing you could do is to cherish it. Take care of her. Assure her that she’ll never regret doing that. Put effort in your relationship and show her that she’s really lucky to have you. Protect her. Love her. Treat her right. Respect her.
