After getting burned and licking my wounds the biggest thing I can advice men is to communicate with your partner or girl you're crushing on hard. Chances are (especially if she's under 30) she's digging you too especially if youre getting drunk and Y'all high key groping each other or she walks around with her friends talking about this is the man in my life. Even if it isn't that obviously just go ahead and address it. I'm coming to the realization is that an alpha male is a man who is a doer, protector, interesting, and most important communicates what they are thinking and feeling. Building attraction is great but you gotta communicate your interest boldly (at a opporturn, appropriate time). That way, if you actually like the girl the relationship can start on the right foot. Women expect men to lead, so do it. Women also expect men to grow and evolve so do that too.
Based on my experience and talking with female friends and family some girls just aren't ready for a man whose an alpha and mature. Communicating your intentions also weeds those women that just aren't ready.
Also don't be afraid of rejection especially when you're high functioning, healthy man. A lot of times it isn't about you, it is about them. Obviously the only way you will know if you engage in calm dialog with her. If you can't engage in calm dialog you probably aren't an alpha male and you need to mature
