[applying to OP, have not read other posts yet, so sorry if I repeat others]:
If I could cut off my sex drive I would. I don’t want to feel this way! I don’t think it is shallow to want sex and it is a very very important part of marriage. So important in fact that if you can’t have sex you can’t get married in the Catholic Church!
I refuse to agree that it is a “happy extra” in a marriage.
In answer to your question as far as I know he hasn’t been unfaithful and he doesn’t send us into bankruptcy though our finances are dreadful at the moment.
I agree you should keep pursuing this in counseling, and if you are not sure how Catholic your counselors advice is, take the advice to a Catholic priest to be sure. Scripture says,
Never tire of doing the right thing. Ask God for His help with that, which is His desire - that you continue to do the right things even when its tiring, like you have been. He will give you the grace to do His Will. The Sacraments are what you need, so be faithful to them, they will be your supernatural help in this.
Scripture also tells us to “Be angry, but sin not”, and I would that an extra step further to say it probably also means, “Be sad and unhappy about your husband’s lack of interest in marital intimacy, but sin not”.
Stick with this unhappiness and keep taking it to the Lord and seeking the answer. It may have many layers. [It may be ED, but consider natural solutions to that, not Viagra, please! Seriously, do some Googling and you will discover there are other solutions.] Plus I think you can enjoy intimacy before that problem is solved, anyway. Its lack of desire that is his problem.
Ask God for comfort and patience that it will be solved, as you pursue it, turning up nothing firm (oops! Pardon the pun!) at first, probably.
Yes, you are right, you should refuse to believe that sex is just a “happy extra” in marriage. Somewhere in this forum I discussed marital sex and a man here wrote beautifully of his love for his long time wife (they are grandparents) and how he loves her so much and their children and their life, how he even loves just seeing her it the sitting in the same room with him working on a project, the sight of her makes his heart happy. And, how they love their time together in the bedroom. He wrote, “Sex is the goods of marriage.”
It struck me that is how marraige is supposed to be. Yes, I agree with you, sex is more than a “happy extra” in marriage!
You are longing for the greater good of marriage which is how God designed marriage to be. You sense the truth of your situation; something is missing, something is not as it should be.
I had a “:marraige”, soon to be annulled, that never was this and never could be. But he was living what it is supposed to be. So fulfilling in every way, including in the bedroom. That is the “goods” of marriage. I thin he is right, and i think you do, too, and that is why when all other things are well, its not okay with you that this is not well.
So I hope you can stick with the problem patiently and keep asking God for His help and trusting him.
I saw the movie “Hope Springs”, with Meryl Streep, this summer, and you might like it. It sort of speaks to your problem. Its not a Catholic solution, but there is a truth to the intimacy difficulties, and a deeper truth to the ending scene which I think you will get. And there is truth to the middle of it, where you see that its a* journey*, not an easy one, and that sometimes things get worse before they get better. I think it might inspire you!
