Search Results: liking an ex

My ex boyfriend recently contacted me. Our relationship has been off and on between us. He's acting like he wants to be in a relationship again. He says all this nice stuff and how he really likes me still. But i can't trust him. All over twitter and facebook he's talking to other girls, and liking a lot of girls photos with like nothing on. He's a 19 year old boy that goes out partying a lot. So i don't expect for him to be stay loyal. I haven't seen him for about 2 months. We live about 20 min. away from each other. I have no doubt that if a girl came up to him to kiss or whatever, he would. I think he's using me as an ego boost, or he's using me for now until he gets a girlfriend. I do know that he wants to sleep with me. He is always going on about missing me. And how he wants to see me. But he doesn't care, like i do. He like leads me on getting my hopes up saying all this nice stuff and than the next day on twitter or any social media is talking to other girls saying theyre cute, i dont know what i shoukld do at this point. It hurts really bad and im very confused. If he messages me should i ignore him? By the way, im 17 and i dont do any drugs/ drinking/ partying, like my ex does.
