<human>: Both 20, male female, 8 months

She just broke up with me because I was trying to tell her something about a past relationship that I thought was true. Ive had a very exhausting day. We have been having issues for all of summer and it is her thinking about me and my ex. I have been nothing but good to the girl and I trusted her with everything I had. I have lied in the far past about that relationship, I can barely even remember it. Anyways, she hates me now and tells me so many things that are basically making just want to fucking kill myself. I loved this girl more than anyone in the whole world, like, I would have married her. She was perfect. But then she breaks up with me and tells me this. She thought I was the biggest loser when she met me and went out with me only because she thought I was a virgin, turns out im not. Ever since then she has been with me only because she didnt want to seem like a bitch. We have done things, up to third base, and I honestly thought it felt like more than what it was. It felt so special so right and I felt so close to her. Turns out everything we have done was only practice for her and she was curious...it meant absolutely nothing and she has told me that she did those things with me because she loved me. She also said she stopped watching porn and of course I believed her, nope....everyday all the time....and she told me I was her first kiss, nope, and apparently she used that guy for practice too. She never ever told me about this guy. I have done everything for her, I slept in my car at her college when i didn't have a room, i drove down 2 hours to see her and drive back up the same day. Ive done literally everything for this girl...love poem, you name it. This is kind of a rant I know...but I have never felt so shitty and worthless in my life. I just need advice or sympathy or something.

Give me the gist of the text in a nutshell
<bot>: I have been lied to completely and fucked over by the person I seriously thought about a future with. I feel so used and terrible. I need sympathy or support.
