Cheating

I am sure my husband is cheating on me! Yesterday I found his ring on his home desk. He is always "working" late. Frequent "business" trips. He comes to bed after I have gone to sleep, if he even comes at all. Rarely answers my calls during the day.
The sad thing is, it's his real true love, I can't compete with HIS JOB. Another woman, that would give me some sort of understanding, something I could compete with, but NO. Just his computer and his job. The love of his life! Oh and the excuse behind leaving his ring, it hurts his finger when he is programming. Stupid Job!
I almost would understand if it were another woman....
