Thank you for your post. It's refreshing to read another report of honest self-appraisal.
How we live out our lives is between us and God.
There are some that are happy to lead a singular life, but I would have to disagree that you don't have anything to offer. Our particular strengths, which may be that we are less inclined to be flippant, more reserved, don't give support to worthless talk and innuendo, will often bring a balancing influence into the lives of those that have opposite traits, that if allowed to run unchecked will run into error.
In the body of Christ, no one cell is allowed to opt out, unless the rest of the body is full of cancer. In that case it is better to extract yourself from that to remain attached to the Head, and retain your good health.
In my opinion there's a lot of confusion in the church as to what it means for a man to be the head of the family. In truth, for a Christian man to be a true head of the family, he needs humility and a drive to please God in every matter, and stand for God's ways rather than bow down to any evil, no matter what he is confronted with and by who. To do that effectively he will need to study and respond to The Holy Spirit's counsel, and have a dynamic relationship with his wife that acknowledges her as his equal in Christ Jesus, and discusses with her all the aspects of life affecting them. He needs to work towards a collaborative understanding of where they need to be, and what they should be doing, and always in exercising godly attitudes and behaviour.
Male headship in a Christian marriage is more about spiritual headship, and therefore the man's obligation to find out Who God is, and what His expectations of us are in respect of our attitudes and behaviour within our relationships, and our faithfulness to Him. If we do that, not only will we be loving our God, but we will be loving our wife to the full, too. Similar requirements are relevant to a woman in marriage, so that she has the wisdom of God with her to help her manage the matters of family and home, and provide spiritual support to her husband.
Shalom, Tony
