Welcome to Grace Centred, @MJ
Since your husband spoke of wanting to find God, then it would be educational and constructive to your marriage if he would agree to starting an Alpha course. Alpha courses originated in the UK, but now are worldwide and being run to cater for for various Christian denominations. See Wikipedia: https://en.wikipedia.org/wiki/Alpha_course
First though and importantly it would be beneficial if both of you arrange a time to talk to your church minister or Pastor and take whatever guidance is offered. Usually a senior church elder is present where a married couple are going through a hard time. There may be subsequent meetings. If you sought the pastor where you first got baptised, this might be useful.
Your husband's passive-aggressive behaviour is unacceptable, therefore discussing your marital problems with a church leader would be for the best: for him and for you. There is no room for aggressive-manipulative controlling attitudes in any relationship because it simply is not Biblical in accordance to our Lord Jesus Christ's teachings. If, however, your husband does not curb his appalling behaviour towards you after your seeing a pastor and exhausting all other avenues, then I think you will have every right to walk out and leave your husband.
I hate to say this, but the cost of divorce is very expensive and you would need a lawyer, especially as your husband could turn even nastier. This is why you must for the sake of your marriage first seek spiritual counsel, and I promise to pray for you.
