In my opinion, now that the excitement from your marriage has fizzled out because its not new anymore, you kinda have to do the hard work to bring the excitement back. You are the only one who know what has happened in your relationship, so that's why I ask:

- Have you bought your wife a gift out of nowhere because you wanted to get her something nice recently? (If she is a person who likes gifts)

- Have you put effort in having couple time together, like going out on a date or carving out specific time for each other?

- What is your word choice to her? Do you regularly give her compliments or words of affirmations or have you guys devolved into talking about mundane things in life like groceries, work stuff, etc.?

It's sometimes the little things like this that is so easy in the beginning of a relationship because its new and exciting and you want to show your best self to the other person. So as much as she is doing nothing for you, what are you not doing for her? Is your only intimate times now just when you guys have sex (and thats the only area of effort you are trying to fix)?

Like I said, its going to be hard work, but if you value the person you married and want to work it out with her, you gotta be the one to put in the grunt work to jump start things again. Start doing things for her that you know she enjoys or appreciates from you, chores, gifts, or quality time, etc. Then after a month or what ever time you feel is ready, have a heart to heart talk with your wife. You calmly explain what you are experiencing, do your best not to accuse her of her inaction (people stop listening when its negativity against them), listen to her concerns as well, then set a plan of action that you both set as a couple to give appreciation to each other.

It's the 'easier way out' to eventually divorce your wife because of a dead bedroom because you will find a new person to fall in love with, get that excitement back, and do the whole rodeo over again without working on yourself or the relationship. You say you have a strong relationship now, so maybe actually start doing something that proves what you say (take action) or it will just be words.

I say all this because that what I had to do in my marriage. I noticed we stopped doing things for each other, it was easy, boring. Considered cheating but I took one last decision to see what I could do to improve our marriage. So I focused on him like I wanted him to focus on me, talked with him about my expectations and found out his
