So recently found a new job. Got to know this girl at work and we hit it off instantly.
I'm always very confident with girls and am able to pull very easily. At work I'm known as the new guy that every girl wants to know, etc. etc.
I've been a fitness athlete for years, played soccer on a national level and I do kickboxing. I have an athletic physique, am tanned and have a semi-italian look cause my mother is Italian. 'It makes girls melt' is what they say.
Anyway just want to make sure this is not me bragging it's just the way it is.

So this girl at work is like a 9.5. I really wanted to get to know her, not just fuck for one time cause I thought she wouldn't be into that. Shit happened where a relative got diagnosed with cancer and her head was all over the place.
She told me we'd better off being friends cause she couldn't have her attention towards me and I was like cool. However, there's too much chemistry between us so 2 weeks later ended up fucking at my place.
2 weeks after that she gets back from holiday and during her holiday she was messaging me every day basically begging if she could come over the day she came back. Invited her over, had amazing sex again.
So this week she has her period, but she already mentioned last week she wants to come over next week. But I'm starting to feel quite annoyed when she doesn't message me or when she sends me messages how she thinks I look amazing at work again... She even tells me how 'beautiful our kids would be'...
I'm like well, if you want to fuck then come and fuck, what's the deal? But stop talking shit about children or how I would propose to my future wife, like wtf?
I'm very direct to her and basically just say whatever the fuck I want and she isn't used to that but that's what she finds so attractive: my confidence. This girls' head is all over the place basically.
Never in my life have I ever felt like becoming a bit weak and wanting to be 'nicer' towards a girl who I wasn't in a commited relationship with (prior to finding out TRP).

I'm quite new to the red pill but I really recognize myself and my behaviour with TRP. I'm very easy in chatting with girls and never do I feel not confident enough to just say whatever it is I want to say and get what I want. I'm just craving to fuck her that's all I need/want right now, but my head is getting in the way. Help me guys I don't want to become this beta kid.

TL;DR: this girl is making me question myself and my abilities. How the hell do I go further with this? We have had the best sex I've ever had it's insane, from both sides. I want to keep fucking her potentially ending with LTR but for now I'm just craving to fuck her. Help me out guys I'm turning into this beta cuck guy.
