Now, I really don't like calling people "alpha" or "beta" because I know there's generally no such extremes of each and that people exhibit a multitude of behaviors that can be considered "alpha" or "beta".

That being said, my LTR's brother-in-law is PRETTY DAMN BETA. He has pretty much given his balls up to my LTR's sister. He does all the cooking/cleaning even though both of them work full time and pretty much is a complete people pleaser.

Obviously it's hard to understand this behavior without talking about my LTR's sister. She most likely has narcissistic personality disorder because she throws tantrums the minute she doesn't get her way. She also talks to her husband in this baby coo-coo voice and whenever they do something together(Anything!), she asks him "are you happy?", in which he obviously responds affirmatively. She also expects everyone in the family to cater to all her needs, otherwise she starts crying. Also, she is 5'2 and ~200 lbs if that helps paint a better picture.

In short, this guy pretty much has to walk on eggshells and whenever he suggests something that is contrary to his wife's desires, she gets incredibly pissed off and moody and acts like a child.

Now my LTR talks to me about this and makes it seem like it's so great that he's a people pleaser and that her parents love him. As for me, I was pretty bluepill in the early stages of our relationship but now I have become more dominant in the relationship. Furthermore, she also talks about how happy this guy is with his wife. He always likes hugging her and showing a lot of PDA, even touching his wife's fat stomach lovingly (I am not making this up, I swear).

In short, how do I deal with the constant comparisons? I have not met her parents yet so one other aspect is that she is worried about how I would come off to her parents if I am not as "friendly" as this guy

Thanks
