To whomever the shoe fits,
I want to start by saying that she is one of my best friends. And as her friend, I'm going to stand up for her when she can't do it for herself. I'm going to put her best interest above mine, even if that has negative repercussions on my end. I want to help steer her in the best direction that I can.
If you ever read this, I'm certain that you will roll your eyes while reading and think that it's not even close to true. But I also know you think that what you're doing is "fine," that it's "harmless," that you're "not doing anything wrong." But if you do read this, please, I beg of you, stop.
Stop acting like she's the only one.
A really great song exists called Girl At Home and the main theme of the song is along the lines of the chorus, "Don't look at me - you've got a girl at home and everybody knows that." You're not fooling anybody, we all know what you're really doing. A girl here, a girl there, another girl on the side. Keep them away from each other, don't let them meet, and it'll all be okay. You'll have a girl everywhere you go, right? Tell each of them that the other girls are "just friends" and nothing will ever happen, right? It saddens me not only that you think playing multiple girls is okay, but also that you think there's no problem in letting them all know about each other with a thousand little white lies in between.
Stop leading her on.
Leading someone on is a downright dirty thing to do. There is no grey area when it comes to questions that should have a simple "yes" or "no" answer. There is no "well, you see, it's a complicated situation." Stop giving her little glimpses of a relationship, and then tearing them away. Being there for her when she needs someone is great, but how about all the other times? A real hero is always around even when he's not saving a girl from a burning building.
Stop using her to fill a void.
I'm not exactly sure which void you're trying to fill with her. Do you long for a true relationship but you're too afraid to commit? Do you need her as a back-up for when you're arguing with another girl? Do you need her when you miss another one of your girls? Do you need constant assurance that you're a "man" and can get any girl?
Stop taking advantage of her insecurities.
You know her doubts and fears, and you have no problem using them. You compliment her, you tell her that she's beautiful. Let's be honest, she is beautiful, but you know that it means 10x more when it's coming from a guy. You know when she wants to be showered with affection, and you swoop right in to be her knight in shining armor. Except you're not even a joker. Stop playing with her emotions, it's a foul thing to do.
Stop acting like you're good for her.
She deserves so much better than you. You don't care for her like she should be cared for. You don't dedicate yourself to her and only her. You don't lead her in pursuing her relationship with God. You don't care for her safety - if you did, you wouldn't have done the reckless things that you have done with her (and that's only what she's told me about). If you have the slightest ounce of true feelings for her well being, you'll know that when it comes down to it, you're just a negative factor in her life.
If you've read this and realize that the shoe fits, please make a change. For the sake of my friend and yourself, correct your ways. Because one day you'll wake up and realize that she's an incredible young woman with a bubbly personality and loving persona, and that she didn't deserve anything you've been putting her through. You are her Cal, let her find her Jack.
