We do not live together. They think he is controlling over money. He just wants to make sure we can make it so yes he buys wisely I guess you could say
Yes. That is wise if you got a 2 year loan on the house. He wants to succeed in being the family man in using what God has provided for you both wisely.
If you think he is going to be that way all the time as if once you are free & clear of loans that he will not allow you access to the family money to shop, then you need to talk to him about it if you suspect he is going to be that way or not.
And you may want to make sure he has Christ first in His life. A tornado should not have to take that house away before he realizes Who is more important. And recognizing the need to be submissive to Christ in seeking to please you is the will of God, BUT without serving you as the head but Christ as the Head of him, because a wife could become a drug addict or an alcoholic and God would not want the husband to please the wife by being an enabler. Nor would God want the man to just let his wife buy anything to put the family in debt and in danger of losing the house. Usually, the evil spend thrift would demand the husband to get another job and then another job until she is stepping out in having an affair because she complains he is never home. This is the worst case scenario for any man seeking to please his wife as if she is in control over him rather than the husband being submissive to Christ. That is why it is important for the husband to be submissive to Christ in taking care of his wife while seeking to please her.
As it is, a conversation is needed between your future husband and yourself on how he will take care of you. As for not going to church to take care of the house; your husband should know that you can do both when Christ is first in your lives.
BUT, not going to church does not necessarily mean Christ is not first in your lives, especially when the church is not repenting from iniquity or any religious works that is denying Him since you are not to have fellowship with workers of iniquity, but rather reprove them. And if they will not hear it, then that would be a reason why NOT going to church is having Christ first in your lives.
Your husband nor you are under the letter, and so pray for him that Christ will speak to his heart, but do respect him as the head of the family so that he may come to admire how Christ is first in your life, and seek that same relationship with Him.
So ask him about his belief on how he is to handle the money in the family, and then if it looks like he is too controlling; mayhap fear of failure in taking care of you?...then ask him if it is okay for you to get a job, even a part time one and a separate account for you to spend as you please from what you have earned, knowing full well, never to buy anything on credit that you cannot pay in a short period of time without procrastinating in building a huge debt beyond your earnings.
Once you clear the air as to determine if he is someone that is controlling within reason or not,then you need to ask the Lord to help you decide where to go in your walk with Him from there, but if you ever daydreamed about being a missionary or making an impact as Christ enables you, then every believer out there should know that how you walk with the Lord in relations to your family, fiance, and eventually your spouse and God be willing, your children as well, is the first and foremost mission of every believer.
So pray and rely on Jesus Christ as your Good Shepherd to help you shine your light to every one around you, including family, and regardless of bad decisions or fiery trials, you can rest in Jesus Christ that He is in you and is with you always to see you through it when walking through this valley of death that you will not fear any evil because He is with you always.
