I have this friend of mine who is exactly like that! Ugh!A few weeks ago I was at my wits end listening to him ramble and I tried to interject and he snapped "just let me finish!" at me! LOL!!!
I was like... dude, you've been talking for at least 10 minutes straight!!! Probably more!!!
He has Mercury in Gemini and he's an extremely emotional Cancer (Moon conjunct Sun!).
I think I am like this too, but I am really conscious of it, so if I have been talking about myself a bit, I will mak a point of asking the other person about them, or give them a chance to direct the conversation towards something they wanna share or talk about. I have the Sun conjunct Mars and opposed Jupiter and this opposition forms a trine sextile to my ASC/DC. so... yeah... I'm a bit ego driven (Sun/Mars in the 5th too).
The other week, me and the Cancer had a huge falling out (we were FRIENDS... I made that very clear all along), and he launched into this whole "woe-is-me" tirade about all his emotional hurts of the past. I swear he talked for 2 hours and all I said was "yeah, yeah... uuuhh... yeah"... It was completely weird and inappropriate and he had no sense of how much he was creeping me out or how much he was friggin' talking and needed to shut up. At some points, I thought he was crying... it was way too intense and strange, like I set him off somehow...
I only let him continue because I was scared and didn't want to set him off even further. He seemed to have lost it!
Now he's acting like I'm mean, because I've cut off all contact, but just like with a simple conversation, he can't seem to take cues as to when to back off. He doesn't take a hint! He doesn't think.
And with me, he didn't need a hint that was the 3rd time I had flat out told him, we were not heading to boyfriend/girlfriend land. The last time I told him, he acted like I was flattering myself and that he was totally cool being friends.
Anyhow, I think I just did what we were talking about myself (lol).. but really this guy is something else. I feel he really does have good intentions and is a good person, but he's just very subjective or self-absorbed or something, he won't listen to cues or hints from others and he flat out IGNORES what you tell him outright. It's crazy.
This is his chart:
Scarily, I just realized his Mars is exactly square my Sun/Mars. Ugh!!
