For myslef I can't relate to this. My H is the one person I feel close enough too and safe enough with to speak freely. I have approached him during times I was questioning my love for him and my commitment to our marriage. He was the one person who could help me figure it all out, not some third person who has nothing invested in our relationship. Well, that's not reality.
Marriages are tough and they all hit some rough spots every now and then.
Working through things with your spouse can strenghten your marriage. It also helps avoid situations like this one. My H would have felt worse during those times if he thought it was something I was discussing with another man. My H will always hear from me what I feel is wrong with our marriage. It may cause some pain but it will do less damage to our trust and I beleive trust is a major neccessity to a healhty marriage.
