Listen my friend an affair goes no where good. If you do it you hurt yourself, your wife and your family. Ultimately you end up losing it all. Find things that you and your wife enjoy together, don't pressure her, show her you love her and still care. I know you are only 31 so the old clock is ticking away, but don't mess it up. Respect, faithfulness, trust and love are the keys to a healthy relationship. Learn how to listen to your wife, be in tune with her needs, learn how to be emotionally intimate with her. Hang on and enjoy what you have and don't lose heart.
