Thank you for the added information. It helps a lot. I believe I can now be of help with this issue.
First, let me say I can imagine how confusing and distressing this situation must be for you. On the one hand you are both close. But on the other hand your husband feels the need to keep secrets that point to other emotional attachments that he has no desire for you to see. So somehow the emotional closeness is not complete. You are clearly sensitive and intelligent enough to sense this within yourself, that he is not emotionally being complete in the marriage if this is going on. And it is correctly bothering you.
And this is actually the key to my answer to you that you need to consider and think about. Let me help you with a healthy orientation for what you are feeling. We humans are not built to tolerate emotional vacuums. You can see that your husband is filling some emotional need elsewhere or this weak excuse would not be presented to you by a man who is this intelligent and emotionally expressive. So there has been created a vacuum. Your emotional selves feel the void and want it filled. You know that yours is because he is seeking some need fulfilled elsewhere. And we don't know what his emotional vacuum is that he is seeking to fulfill elsewhere.
Your husband may continue to deny this and I do not make these statements to accuse him of sexual infidelity. I do not know. I am writing this to discuss the EMOTIONAL distancing that has been created. The two of you need to go to couples therapy now. There are two types of therapies I recommend strongly for you two to consider. I also urge you to take your husband to Starbucks or some other neutral quiet site and read my answer together and agree to undertake this so that your marriage becomes what each of you wants it to be.
One type of therapy is called Emotionally Focused Couples Therapy. This one is the one I would use in your situation first. Why? Because it focuses on how there have been created emotional barriers and how to get through those barriers. The barrier of honesty is a very precious one that trust depends on. And openness is required for honesty and thus trust. So please consider it before you take other action.
Here is the web address for their therapist finder:
On the website you'll also find excellent books by the founders, Sue Johnson and Leslie Greenberg. You may not find an EFT therapist in your area. So, the other therapy is Gottman therapy. Seek a therapist who is certified by the Gottman Institute. Here's their web address for finding a therapist:
Why? Because John Gottman is the foremost researcher in marriage today and his couples therapy model is the most straightforward model available and you may need that because there isn't much time to see if he will move closer. So if you don't connect with EFT, use this therapy. I hope that therapists working in these types of couples therapies are listed for your area. If not, find a couples therapist who makes you feel confident in his/her skills and values.
Okay, I wish you the very best in this and in the future!
