Why are Gemini guys so selfish and heartless?

[125]

Ok these two friends mine had a serious argument (cheating) where they was both wrong a Gemini man with a cap moon (high earth based chart in cap) and Gemini Venus and a Cancer female with a Gemini moon and a Gemini venus both have a mars in Cancer (rest of chart a mix of sag and Aries). We all supported him in dealing with the issue he was all fine with that and then when it came to her turn. The Cancer friend was really hurt by it all he on the other hand seemed to not care or take responsibility..

He was all about how it made him feel and seemed to think nothing of what she felt they was suppose to be in love. He even was jealous of the fact we was supporting her too complaining I personally decided to not have a friendship anymore with him at least not for now. This is just the short story he has always been self centered and seem to be cold.
The thing is he was a nicer person to friends then people he apparently cares for and is a funny person to be around well so I thought till now.

My question is why are Gemini men always about them and think nothing else of others feelings and the consequences of their actions. Everything seems to be a game to them even serious things. I have noticed they talk rubbish about others alot and then act friendly to their face. This is based on this Gemini and another I know who not as bad but is self centered.

I actually get along with Geminis most of the time maybe it because I have a Gemini Mercury and Venus.
What I meant when I said cares for is a relationship I think he does value friendship a little as he tried speaking to me ignoring him because of the way he acted to my other friend. I know my Venus should mean I like games with love too. I take relationships seriously if I love someone would only act differently if it was not love..
I will probably end up talking to him again in due time as my Gemini Mercury always wants to talk things through with people. This is not about me it about them and they should be speaking to each other really. I just feel he has acted so selfish even though he is a friend too and when he complained it annoyed me a little.

Guess even my Gemini traits in my chart is not enough to understand what goes through their heads! I get the feeling his Capricorn moon does not help.

Ok so I haven't read your question I'm just giving you my knowledge of geminis trees different ages with star signs.. When my bf (who is a Gemini) was younger he cheated n was constantly changing his mind. And now he's nearly 30 and is the most sweetest kindest thoughtful unselfish! Greatful for love, he is the opposite fb selfish. He's the best! He wants kids n a wife. And I'm a 23 year old cancer who he tells me I'm selfish n im not very loving tbh but when I'm older I will be a typical cancerian of home and love. I don't deserve him and I've told him that I have one child and that is enough for me I don't want anymore or marriage. Our relationship will run it's course but remember age is a big thing

thats just 1 gemini guy thats selfish, but not all like that, if my dad (gemini) was selfish, would he be working up and down the country working really hard a long hours to support his 2 kids and pregnant wife going from london to liverpool to gloucester to coventry?
