I've been pointed to TRP community a couple months ago by a friend and I love everything about it, the truth sucks but I would rather live in reality than in delusion. This subreddit was there for me at my greatest time of need. However, right now I'm confused beyond words so I will try keep it short.

I got into my first LTR (intended to anyway, but ended after 2 months, but we continued to see each other up to 4 months later up until now). I would consider my behaviour to have been alpha male my entire life. I didn't need TRP to consider things like continiously improving my own lifestyle or expressing behaviour that got women to show interest in me, or to have the balls to ask a girl out, but nevertheless I never got emotionally involved with any of them so I was completely unguarded when I let myself fall in love with the girl I'm about to tell you about.

This girl that ended up sleeping with me I got to the bedroom using traits and techniques I would consider alpha male behaviour, but she slowly made me develop a oneitis for her through multiple long term shit tests that made me change who I am completely over the two month period I was formally in a relationship with her. Here's a guy who has turned down multiple HB7/8 girls not brainwashed by society, who'd make awesome GFs, wives, future mothers etc - just to chase after a HB4 (this current girl: rated my multiple independent sources) - having sleepless nights thinking about her and prioritising her over everything in my life: my career as a (soon to be) doctor, friendships, personal health, religious beliefs, etc

She responds to alpha male behaviour and expresses all the bullshit society has taught women to do during their prime days, but she's also very sweet and could make for a good partner in life. She's emotionally very needy and needs attention all the time, me to tell her I love her and how much I appreciate her, unlike some other girls who'd not want this from a guy they aren't in love with. What I've come to realise after she led me on, is that she's not in love with me but in love with her ex (who didn't give a shit about her in any way and treated her badly). It wasn't until recently where she gave up on him 9 months having completely lost hope in getting him back. She tells me we might have a chance in the future to try again, always blames me for a lack of excitement in her life, turns the simplest of matters into huge debates but if she did anything similar (and she has, multiple times) it's no biggie. This is continiously happening even during the post break up phase (which wasn't really a break up in hindsight).

Over time I've learned to be less emotionally dependent on her, went on a date with a few other girls and started to realise she's not the only girl in the world. I'm back to thinking rationally and as a result of my great success in doing so, promised myself I would never sleep with her again or let her step on me unless it was within my frame. She's sexting me all the time asking for attention and wants to hook up for a one off soon. I know that saying no to it will be very hard and leave me dry for at least a few months, possibly also resulting in losing her forever, I was just wondering if there's any chance that actually (and I don't mean to brag) sleeping with her might get her back into a casual FWB relationship (because I've actually become very good in bed, but on the downside even with FWB I would still have to deal with all her nonsense and lack direction in life because she's too delusional to realise it's just casual or she'll just end it).

I don't imagine myself ever marrying her because she would fuck me over down the line (not because she's a bad girl but because she has a shitty argumentative egoistic personality). I don't know whether I should sleep with her or not, as we have many times in the past even after break up - she's shown acts of love and appreciation to me many times. Wants closeness, attention and submission but is afraid to fall in love.

I have no idea where to take this. Sorry for the long post. Any suggestions with good rationale would be highly appreciated.
