[M4F] Begging is manipulation (a very toxic romance)

Looking for someone to play a manipulative, shut-in girlfailure who victimizes herself and begs her way into a relationship. My writing sample below provides exposition, but I'm happy to change everything but the essential theme.

Let's stay toxic!

"You will move out on Sunday. This has been going on... forever, this needs to end," My tone was final. I tried to maintain an impassive look even as I saw your lip quivering, and tears welling up in the corners of your eyes.

Was I being unkind to my 'girlfriend'? You'd been my friend since childhood. You'd moved in a week after I made the mistake of asking you out when we'd been out drinking together.

Two years and fifteen attempted breakups together, you were still living with me. It was always something. Getting fired unfairly for the tenth time. Dropping out of two degrees. Telling me that you just needed just a week.

"B-but you... you love me. You do, don't you? P-please, I can't, no one will ever want me, you can't leave me!"

I pursed my lips at your protests. I still couldn't bring myself to say I didn't love you. I did. But it hurt me, whatever this had become.

I looked around the room we shared. Not only were you unemployed, you were a slob. Junk-food packets near the chair in front of the PC, and a dildo unashamedly placed on the desk. There was nothing wrong with masturbation, but at some point, you'd abandoned propriety entirely, and the smell of your gooning constantly filled the house, as if porn was your job.

"Please, am I not your girlfriend? I... I can suck you off. I know you love blowjobs," You rushed to me, grabbing my crotch, and attempting to unzip my trousers eagerly, and I flinched back. You lifted your two-day old t-shirt, flashing me your tits, and I sighed.

"Y.... you won't fuck me, even? I knew it. I knew it, you hate my body? No one is ever going to love me, no one is ever going to touch me," Your crying turned into sobs.

And I gave in. Again.
