Greetings,
This was a most heartfelt disclosure that should not be taken lightly. Mind you that this is coming from a heterosexual male; raised by a very strong will women, and the product (myself) being a very happily married gentleman.
Let us lay a few things out into perspective. To begin, both individuals must agree that a problem definitely is present. Secondly, you both must want to find solutions. Just receiving some good advice, possible marriage counseling, and having awesomeness "make-up sex" will not fix matters. This will only lead to the sinking of the vessel which you both sail on in life.
Moving forward, both men and ladies such as yourself need a positive and stimulating sex life. We must all understand that we change every day and this accounts for odd behaviors in everyone's marriage.
However, this gives cause to reflect on both your past and what caused attraction in the first place. Just to point out a few self-questions 1. What drew your attention to your husband? 2. Was it a certain circumstance that your husband may have shown courage, defended your honor, or maybe he came to the rescue? Was your husband athletic, eye-catching, did he have epic good looks, and was he dashingly bold? Maybe he could have been the complete opposite; shy, meek, warm, sensitive, and a good listener.
I said all these things because we forget all too often what caused attraction. Trust me, not all people's lists so clean cut. But, its worth the two of you remembering what these sparks of fire were, and how to find a few new ones.
Now, let us focus on you. I'm all to overjoyed that your problem isn't that your husband has completely lost interest in you sexually. That's the "black hole" (the end) in many relationships.
Let's face it, some people have low sex drives, while others need to be heated a bit to get their rocket engines fired up. You mentioned that you work nearly 7 days a week. What deserving wife would not deserve focused attention, pampering, and warmth of a husband's understandings, that you're fatigued? Many so-called men a just little toy soldiers, when all should be combat ready to meet the needs of the lady of their life. It's completely an equal balance but, sometimes a man needs to reach for more than just epic sex.
In your husband's case, he sees you're not present, when you are around he wants you sexually but, your tired. Demanding jobs, income, and status have all been bitter situations for absolutely awful sexual habits, and failed marriages.
A questions that must be researched by you both are 1. What's more important; careers, children, quality of life, awesome sex, and let's not forget each other. I feel you both should have it all. I could truly write you a novel, and thousands of people may send countless suggestions of how to fix your current state of matters but... No one will ever understand your current situation from your perspectives.
There's no golden advice like more of each other. Time is the single most important thing on earth. You're not meat on a bone that only designated for husband's needs. But, like-wise you must also be a driving force that can bring about harmony. I certain you can do that.
A woman is a powerful element. She's wisdom, she's focus, and more times than many... A woman has had simple solutions to fix the most astronomical of problems. I'm sure I might lose male support on this comment, but woman was never intended to be second, less smart, nor fragile. All throughout history, women have been rulers (queens), soldiers, great thinkers (scientists-doctors-religious icons) etc. However, when it comes down to marriage, the woman becomes a captive.
In conclusion, know that you have strengths, and a full outline of the problem. After all, you wrote a perfect post. You both have a difficult list of matters to attend, and best you both find middle ground to stand on to resolve things. Remember, you both have a free will choice to remain as you are, evolve for improvements, or end on very loving good terms. Fight for each other, not against the other, and you both will be able to build new frontiers together someday.
"Coverings & Blessings"
