Hi Green Jade
Please be aware This site has a lot of ex-witnesses on it, who would rather encourage you never be a Witness again and can be very blunt in their dislike of witnesses.
I agree that human nature being what it is, you will find human failings inside of Jehovah's People (or indeed any group) but it is sad if that is the reason that stumbles us from being practicing Witnesses. The reason we are told to encourage each other is because we can fight the pervasive dangers of imperfection together, encouraging one another.
Mark 11:25
And when you stand praying, if you hold anything against anyone, forgive him, so that your Father in heaven may forgive you your sins."
If a congregation is failing in this regard I have seen a certain ones really try and fight it and be extra kind in the face of others giving into less-nice traits, shaming them into repentence by offering forgiveness, love and understanding.
For you to actually bring your kids up as Jehovah's witnesses wanting them to have that personal relation with Jehovah and his son Jesus. It is a long road which is easier if you take it one step a a time. I'll be honest it would involve your own return to witnesses if you are truly determined? Reading the bible and praying to Jehovah for help is a good starting point with knowing what you really want to do.
Daniel 6:11
Then these men went as a group and found Daniel praying and asking God for help.
Understanding that being Jehovah's witnesses is literally about our faith in Jehovah as our God and his promises fulfilled through his son Jesus and being united as a people and flock gathered together.
It is not about being in a social group but about being one of Jehovah's people.
Thessalonians 5:11
11 Therefore encourage one another and build each other up, just as in fact you are doing.
Your husband is right to say it is your decision and yours alone at the moment although I think you will have to reach a mutual agreement on certain things when the kids are involved. He sounds like a nice understanding person which is a good.
I hope things work out for you.
Truly knowing Jehovah our God as his people is a real blessing.
Zechariah 13:9
This third I will bring into the fire; I will refine them like silver and test them like gold. They will call on my name and I will answer them; I will say, 'They are my people,' and they will say, 'Jehovah is our God.' "
