Well, I'm reading something now that I can understand

my ascendant is even cooler now

My husband's sun is on my vertex and my Aries stellium conjoins his vertex.

In terms of feeling that Vertex point -- it's hard to separate for me because my vertex makes my cardinal t-square into a grand cross so anytime a planet crosses it I feel it because hello transiting grand cross.

My husband's sun gives me a permanent grand cross, but I think that this is actually easier to manage than a t-square because it's stable and durable. I need his Capricorn energy to fill a vacuum in my chart. The fact that this is also my vertex point (what I'm attracted to, as Glenn said) just intensifies the meaning for me.

I do not have a lot of experience with this, except that recently I found that I shared vertex aspects with one of my best friends for 20 years. We have an exceptional friendship - never a cross word and we do know what the other is thinking/feeling a lot. She finally found out her time of birth.

Lo and behold her vertex is conjunct my asc. and my vertex is conjunct her asc. My moon is also conjunct her asc. which I think also contributes to the situation.
