As men, we want to provide and protect what we have gained, including our relationships. But if we are insecure in our own strength, that insecurity will seep into our relationship, making it weaker. I have first hand experience of this in my previous marriage and my last long term relationship. I was so insecure that I was going to lose the "goodies" of the relationship I resisted anything that posed a threat. I particularly resisted when my woman had a problem with me.
I've had three 'significant' relationships in my life including the union I am in now. In the past, when my woman faced a challenge, I would do what I've done in every area of my life when there was a challenge. Try to FIX IT! "What do you need honey?" "I'm sorry dear." "How can I help?" "Don't worry about it baby." This never worked!
