Okay so my situation is this: M21 Wife 21

Lately I've been thinking about breaking up with my wife (not married but kinda I'm in Texas) and the reason for it is because my personality and her personality just do not match. Every time I'm around her I'm not me, the REAL me. For the past 9 years she has only seen the side of me that cares about her and not the side that actually wants to have a life and that wishes she wasn't with me and that every night wishes she would leave my ass so I can enjoy life, anyways she's only seen part of me and I don't want to fully show her my personality because I know for a fact that if I do I'm gonna leave her on the spot. I don't wanna leave her because we've been together for so long and she does give head and fucks good and cooks and cleans but godammit it's her personality that just drives me insane. She's like a grown ass kid, her voice is loud af and she's doesn't know how to act like an adult. I can't take her to any serious (for example) family meeting cause she doesn't wanna talk to the adult females and gets mad when I leave her alone to talk to my cousins for a minute and every time I'm off (one day off a week) I spend it asking her what she wants to do because she stays bugging me on what we're gonna do on my day off during the week and then we end up going somewhere pissed off cause we spent the last hour figuring out what we're gonna do and where were gonna go. Also recently we've come. close to ending the relationship but every time I bring up the subject it's like she knows what I want and tries her best not to talk about that and keeps saying things I wanna hear, and also this other time I told her straight up that I was DONE that I didn't wanna be with her anymore she got to crying and begging even getting on her Damm knees and beg to stay, I didn't know what to do so I said yes but godamm me if I don't regret saying that everyday single day. Anyways I'm just tired of her, I love her and all but I feel it, I feel the vibes and it's getting closer and closer to a break up.

For you guys that say "oh she does everything clean, cook, and please you why are you leaving her" I can do all that myself and I don't mind being alone and I have a good job that pays 2k a month. I lived in a room by myself for 7 years when I was living with my mom at her Apts so being lonely doesn't affect me, and yes I do have friends I'm a stoner.

ANYWAYS, guys what would you do in my postion? Y'all can ask questions to have more backstory but please I need help I don't know what to do.
