SOme years ago, my wife asked me about my poker playing (online) and decided she wuld like to play too. Now she does, BUT we do not play together. Her approach tends towards cautious (tight passive) whereas mine tends to be the opposite. She often gets “To the money”, I do not get there as often as she does. However, if I do get there, I will win 50% of the tournaments I do get there in. She very rarely wins a tournament, but “cashes” far more often than I do.
If she tries to do it “My way” she fails. If I try to “Do it her way” - I fail. Although clearly if we could combine our strategies, with her “Getting to the money” then me “Playing the final table” we would maximise our earnings. However we have not fynd a workable way of doing that as yet.
If we sit together and one of us tries to play, the player is influenced by what the player thinks the “observer” would do. It is simply not workable because our base strategies are different.
I guess we are both “Emotional”, but I chose “fight” more often and she chooses “flight” more often.
This in my view fully accords with the “Evolutionary psychology” of the sexes, with man as “hunter” and woman as “Gatherer / nurturer”.
There have been studies which showed women to be better “investors” than men - because they tended to buy and hold but less frequently, whereas men “traded” and lost a lot of cash to “commissions” (in our case “spreads” )
There also seems to be some evidence that men tend to be more emotional than women - across the world the statistics are consistent, showing a lot more men commit suicide than women. Also in divorces, women are usually far quicker to “rebuild their lives” than men.
So what I am trying to say is that it is good that as @eddieb says, you will have someone to talk to. Many of us are here for exactly that reason. This can be a lonely addiction !
The big BUT is that you must each find your own strategies and instruments to trade. Do not try to do it “by committee”.
By all means discuss and co-operate, but each develop your own timescales and startegies. Do not try to “Compromise” - unless your personalities are identical (Almost impossible - remember “opposites attract” ), any "Compromise will be counter productive.
My wife has no interest in trading.
Some good thought processes shown in your original post - promising 
Hope that helps.
