I know it's unbiblical, but so is getting divorced and remarried but many Christians do it
This is the crux of your predicament.
What shall we say then? Shall we continue in sin, that grace may abound? God forbid. How shall we, that are dead to sin, live any longer therein? So you admit it's unbiblical, but care more about yourself and what others think, and so you're here soliciting their opinions. You're conflicted and, if this situation is not dealt with spiritually, it will not end well for you.
This is less about age differences and more about biblical headship-submission roles as established by The Boss for our protection. The Guide is there because The Boss doesn't want us to get hurt. He has a spiritual order that, if violated, will result in destruction to one degree or another.
Evidently, your flesh is attracted to the current situation. Have you ever examined
why? But who/what should you rather be listening to and obeying? You've already told us the answer to that, while a double minded man is unstable in all his ways.
There is a way which seemeth right unto a man, but the end thereof are the ways of death
. My counsel is to choose God's way and be blessed - or not.
