<human>: Can you give me a shortened version of the text?

After two and a half years of dating and four years of work put into this relationship, my ex breaks up with me out of the blue. I say out of the blue because everything seemed to be fine on Tuesday, and then he broke up with me on Thursday. 

During our long conversation, there were lots of tears from both of us, and he said he just wanted to be alone. That's ok, I can understand wanting to grow outside the relationship. Find out a couple days later he is already with someone else he barely knows. 

Fast forward a few more days and we're talking and he's holding me and telling me how big of a mistake he's made...yet still doesn't break up with this girl. He tells his friends that he's just looking to get in her pants and then turns around and tells me that he really wants her. He claims he doesn't want me anymore but calls me a temptation anytime I'm near him.
<bot>: Ex broke up with me with no warning. It's like a soap opera; I'm confused and would love someone else's input.
