Well, at least you are being made aware early on as to your husbands intentions toward and for you. And thank God you don't yet have children with him so as to enter into that fight he's forewarned you is coming should you have.
Speaking for myself, and as a married woman for a great many years, you entered your marriage to be a partner, not a slave.
The scriptures tell us when we marry the two become one. Your husband appears not to realize that. He appears to think, according to what you have shared, that you are less than he in matters of rights and place in the relationship.
That's contrary to what God's words tel us should be so in a marriage God anoints with His blessing.
That being said, what I also found concerning in your post is that your husband is set on staying in his old church that he left for some reason before meeting you, and his old girlfriend is still there attending.
And, while he sounds like he's all for you finding a church that fits your needs, he's implied threats toward your independence in that area by now saying he'd like you to sign a post nuptial agreement so that he takes, takes, takes, from you should you not hold to his rules. This would also apply should he decide to divorce you, if you entered into such a contract.
That should have sent up huge red flags! Because now you are married and there he is talking about division of assets, your kids, in a divorce. Which means he's thinking of that for your future. That's a big warning that he's not thinking of staying married forever. He's thinking about how he can benefit over you when you divorce.
The Bible tells us we are not to be married to an unbeliever. That is grounds for divorce. As is infidelity.
I'd say you've been told by your husband that he is not a believer in the manner of faith that includes your future. He wants to hold dominion over you including where and how you worship.
Get out! That's my advice because were it me, I'd write your post after I'd packed up and left. Speaking in past tense as to what should I do and is it wise to consider reconciliation? However, your husband has already told you the answer to those two points. No!
He's the boss!
You didn't marry your boss. You married your equal. Your husband does not believe you are one. He believes you are two and he has dominion over you.
When a husband tells his wife he commands where she worships, she's being told her husband has decided how she see's God, where she will honor God, and how she will hold faith in God.
He's playing God!
That's idolatry and blasphemy.
You didn't sign up for that.
Pardon the pun but, run like Hell!
The man you are meant to find is out there. The man you're with is an example, God bless him, of what NOT to settle for in a relationship.
I bet he didn't act like this while you were dating did he?
When someone shows you who he is, or tells you who he is, believe it! Because no matter who they are, they've been themselves all their life. We come into the picture much later and are only learning who they are by what they show us. And sometimes, all that is an act so as to get us locked into a relationship with them. Once that's assured, the real man comes out. He hides prior to that because deep down he knows, either intuitively or through past experiences with women who fled the real him, that who he really is will not be tolerated when a woman is free to walk away.
Such men think that when a woman is married, she's property and his forever no matter what.
That's when it can get really ugly and really dangerous.
God be with you.
