So I picked this girl up at the bar, brought her home using "lets go back and cuddle". Anyways, she ended up being on her period so we didn't have sex. So I texted her a couple of days later and we set up a date. I picked her up, drove her to my place to check showtimes on the laptop, had a fairly passionate make-out session and I said "we should go" since I knew it would be there for me another time. I paid for the movies and dessert and at the end of the night (it was Monday and I had work the next day) dropped her home. The next time she came over we had GREAT sex, like the best I've ever had, she was shocked at the end clearly her best as well. After a couple of nights like this of just sex and ordering pizza (she hasn't paid a dime for anything so far) we decide to be exclusive but she says that she doesn't want to be a house wife cause she got out of a relationship and wants to make sure our expectations are on the same page. I said my only expectation is you don't cheat on me. She said well yeah, i mean besides the obvious ones. I said that's it. So we date for a few months, I'm pretty much paying for EVERYTHING even go to Cuba with her and she messages me one night after saying how she's really a softie, she's just putting up a guard, she really thinks the perfect life is family and kids and she's afraid to lose me because of this guard she puts up. I respond saying I want her to trust me and I'm not going anywhere "you're my baby ". She responds saying that made her cry. So move forward we get to a point where I get pissed that she's always going out with her friends and this guy. I had a bad feeling about it. She promises I have nothing to worry about, cries even one time when he calls her while we're together and I say pick up. She grabbed her phone crying and locked herself in the bathroom for a minute. Said it's because she can't handle confrontation and they're just friends and he's prolly calling to brag about something cause he's "like that" and she even thinks he's gay. I am a complete idiot for not listening to my gut. So a week later we get in another fight, she says she needs time to think. I give it to her. We meet up after a couple days of not talking, she says she's an idiot, that she shouldn't take for granted what I'm offering and wants to be with me. We have the most amazing and emotional sex I've ever had and I ask her again if she's sure. She looks at me and says "I meant it". We go out again that weekend with mine and her friends and something's off. Calls me to break up with me a few days after. I then go to her place the next day to exchange stuff, tell her we don't have to be serious, she says well that's what I wantED and that we can't go back. I end up seducing her into sex. I ask after, "sooo are we seeing other people now or?". She says "Do you want to see other people?" I say "Well no... but.. like" (thinking well you did break up with me ). She says "well I'm obviously going to say no now after that sex (she orgasmed again, we generally just had unbelievable sex always), nothing else will be good enough". I say well we should talk about it, she says we will. I call her a week later to see what's up, she finally admits she has feelings for that guy I was worried about. I tell her she's a lying bitch. I look at her twitter after and they're dating, saw a pic of them holding eachother the day after I went out with her and my friends and this was at an event we had a fight about her going to with him getting her and her friends tickets. She posted some shit (I don't have twitter by the way) about how I shouldn't be surprised she fucked me over #dumbass. So, clearly I made a million fucking mistakes, but I had such great luck with girls for the past 7 years that I felt I was untouchable and completely ignored any rules and was completely direct and open. I set myself up. So lay it on me guys, yes this is embarassing, I got played but I literally could get anything I wanted for the past 7 years that I just got sick of playing the game and wanted something genuine. Clearly I picked the wrong girl and ignored a million red flags. Lay it on me boys, I'm an idiot tell me everything I did wrong (yes a lot of it is obvious like paying for everything all the time and making her the prize the whole time) but I've started reading "The Game" and watching "The Pick Up Artist" and now I've never been more motivated to meet girls and have a pool of options. I'm done being a nice guy. I go through phases, I'm nice till I get fucked over, then I'm a player till I feel bad about how I treat girls, then I'm nice again till I get fucked over. I just got fucked over. Thoughts/Comments?

"I said my only expectation is you don't cheat on me."

Why would you say this? I feel (I'm no pro) this shit just happens and is assumed, don't worry about it, don't set rules and don't be so concerned. Actions speak louder than words, obviously you don't want her banging other guys (maybe you do, whatever floats your boat) but that line, in that conversation, is weak and needy. That's how I read it anyways.

Seems like you are needy and untrusting by nature with women. Why?

I said that as in a "What do you mean what are my expectations? Just exclusivity I don't know what other expectations to have right now" kind of way. That's what the conversation was like, it wasn't me just directly saying please don't cheat on me. I don't well at least I didn't have trust issues before her, but my intuition and gut were just subconsciously picking up signs that I can't trust her but consciously I guess I just wanted something else to be true.
