While it is natural and perfectly understandable that you want to get your heavy thoughts off your chest, and confide in friends and family, you should do so with caution. There are two reasons for this. One is that you need to make sure that the person you choose to confide in will not gossip in any way and spread the word, and may be ultimately lead to your spouse knowing. Secondly, it is not uncommon that your cheating spouse is involved with the very friend that you are confiding in. Hard, I know – but it happens all the time.
