So here's the thing. I am a terrible human being. Like, I know, it sounds harsh but that's exactly how I feel. I used to hold proud on who I was as a person, great and the love I have and how I treated by boyfriend of three years was out of a movie. But he wasn't the same. My boyfriend, let's say his name is Mike. Mike is wonderful, loyal, good looking, loving and oh yeah, loyal. This man is the most loyal thing I have ever seen. But, he has bad anger issues. Terrible. He used to treat me like shit, yell, throw things, insult me and even laugh when I cried. I was tired of it. So I left Mike. In comes David, a great friend of mine who has always had a thing for me. I used to have a crush on him before my relationship started but it died once I did. David found out I was separated from Mike and that was all he needed to tirelessly work at trying to gain my attention. I, on the other hand, was battling to stop looking for Mike, all he did was hurt me and I kept calling, asking to see him. And so, I took on David as a distraction. After days, weeks, months, David became my partner for everything. Errands, sex, he was like my boyfriend. And I was slowly falling for him. At the same time, however,  Mike was correcting himself and the change he made was unrecognizable. He was another man. Another, great man. I left David, to go back to Mike. Mean, I know. But love conquers all, I think? Everything is wonderful. Mike is great. But I keep talking to David. Mike is aware but not happy, but he's so bent on being the greatest guy in the world that he says nothing, he politely asks me to stop. David and I were strictly friendly conversation but the other day, I saw David in his car. And we ended up having sex. And I don't want that. I don't want to be a cheater. I want a good relationship with the man I love but I can't seem to let go of David. And I want to, I just don't get why I don't. I've tried stopping speaking to him but he writes and there I go again. Please, spare me the insults, I just want an opinion as to what the fuck is going on and what I should do.

Thanks, sorry if it's a little hard to understand, tried to squeeze a year's worth of disasters into 7 sentences. (I think)
