Most Helpful Girl
Have nothing to do with this guy. He's saying this just to keep you around. He means that he's not mature enough for a relationship and thinks that they are to much work that he's not willing to put in, but he wants to keep you around so that you do everything you would if you were in a relationship and become emotionally attached, while he acts like he's single and if you ask him about it, he'll say 'but we're not dating or anything'.
You are so much better then that and you do not need a man around to treat you like shit. You are strong and beautiful and just tell this guy to go fuck himself. You are smart and independent and do not need such negativity in your life. I hope everything turns out ok
