Please do not leave your husband. I read your story and it was the only one I felt I should answer right now. You have stayed married for 27 years. Such a long marriage is rare nowadays and it means that there is the special bond between you and your husband even now it seems to be all lost. Your husband cannot communicate with you and he needs help for that. The best thing to do is to make appointment to marriage counsellor. You can find the best ones from your local congregation. Your priest will be happy to help. And if you do not have a congregation yeat now it is the best time to get one. You also need friends good female friends not males. Please forget your ex-colleague. He has a wife and he needs to stay loyal with her. Actually, the first thing you should do is to forget him once and for all. Try never think about him. If he comes into your mind please pray Jesus to help you. It is not from God,you know that. The second thing you should do is like I said to find local congragation. Speak to the priest there and try to find good, Christian women to become your friends. If there is no marriage counselling in the congregation you should make appointment to another counsellor. Pray that you will find the right one. Yellow pages and Internet are full of licenced marriage counsellors and there is one for you too. Remember you do this to save your marriage which is the gift from God even it seems to be just a burden right now. If your husband does not agree to come with you to the counselling just go alone. You will learn how to communicate with your husband because the problem in your marriage is communication. Also ask one simple guestion from your husband: why are you angry with me all the time? Have I done something to hurt you? Say that you would like to ask forgiveness but you cannot because you do not know what you have done. Maybe it was something so small you have forgotten, something what happened long time ago but it meant so much to your husband. This can be the new start for your marriage. I wish that this New Year can be the year of recovery and love for your long marriage. I pray for you and your marriage. Just know here is a friend who prays for you. Sometimes that helps too.
