I’ll have a go at answering this. First of all, humility applies to both men and women. There’s nowhere in the Bible that instructs women to be humble without it applying to men too.

Philippians 2:5-11 gives us a good picture of what humility looks like. It is letting go of our right or position, and lowering ourselves in service to others. Jesus role-modelled humility for us when He became flesh and gave His life for us. So humility applies to men and women equally.

So humility is certainly not timidity. Jesus is definitely not timid but yet He is humble. 2 Timothy 1:7 says “For the Spirit God gave us does not make us timid, but gives us power, love and self-discipline.”

Instructions around dealing with anger in Ephesians 4:26 also applies to men and women equally. Anger by itself isn’t a sin. But when we say or do things harmful to others out of malice, then it is sin. So Ephesians 4:26 gives us instructions on how to deal with anger.

There are passages that give instructions individually to husbands and wives in terms of attitudes and behaviors we are to have towards one another. 1 Peter 3:1-7 provides some good guidelines. Also Ephesians 5:21-33, and Colossians 3:18-19.

Hope this helps. @hope777 might have some advice around this too.
