Advice

My husband and I been married for almost 3 years and for some time now we been arguing more than anything else. He confess that the sex is boring to him as it is to me as well. We've tried married counseling, we've tried dressing up during sex to spice it up, he found a job, but nothing is changing I'm really believing my next step is to file for divorce. I can't and I won't keep putting the effort forward to better our marriage if he refuses to change.

Any Advice or Should I just let it go?
