Six months ago I met this guy online. We're 3 years apart and live 400 miles away. We hit it off from the start, and he was became flirty fast. He admits he's a huge flirt, and that he had cheated before- but he says he believes everyone deserves a second chance. He was quick to tell me he liked me, a lot; and eventually it became love. He'd tell me about how great I am, he'd call me babe/baby. He asked me to be his girlfriend recently, I said no because of my problem with his ex. He was a lot more experienced in relationships than I was. He told me about it, often. At first it didn't bother me, but once I started developing feelings for him it became a problem. He constantly brings up one ex, Susan, who he said he'd been with for 2 years. He says it ended because she left him for some other guy. He sent me a picture of a list of 100 things she loved about him that she made for him (but also added "idk why I still have this"), he's sent me a picture of her and insisted she's pretty, he's talked about how sex was with her, when I don't want to do something like send him nudes he says "it's okay, I still have hers" - after I get mad he says it was a joke, when he says he loves me he compares it to her- he says he never really loved her. She started texting him again wanting to be friends, I told him to reconcile but he said that if he did he knew he'd fall for her again. But now he keeps talking to her, and on top of everything I listed, he constantly sends me screenshots of their conversations. Not that this is significant, but her name went from Suzz to Suzzy on his phone. When she pointed out that all he ever talked about was me he insisted to her that I wasn't his girl. I started getting mad every time he mentioned her. But he'd beg for forgiveness and insist that I'm the only one he loves and wants to be with and that she's just a friend (every time). But after every time of me getting mad he continually mentioned. He knew that it made me mad and he said he hated making me mad, but he kept doing it anyway. I told him that we should end whatever we have and he swore he'd never mention her again and that he'd completely erase her from his life because he didn't want to lose me. I'm still convinced that he still has feelings for her and now I don't know what I'm here for anymore. I've cut down on the flirting because I feel like I'm not who I thought I was to him and he's noticed and asked why everything feels different. I feel like he's just lusting over the idea of me but that he really still loves his ex. It's breaking me cause every time I feel like it's time for me to let this whole thing go, but he always convinces me that I'm everything to him and he can't be without me. What am I to him? Should I stay or should I go? I think I do love him, but don't know if I can keep dealing with this..
