I have name changed for this and you will probably understand why.
DH and I are into our 20th - odd anniversary.
When we had been married about 8 years I had an affair. I am deeply ashamed of this and am only posting to say to some people that if you and DH / DW want to get through things (jointly) it is possible.
NOT an excuse , at the time I was very severely depressed and drinking too much. The depression made me think I could get some escapism , the drinking clouded my judgement. This is no excuse. I am lucky in that DH took the problem in the round. He told me all the issues which he thought needed to be fixed. I told him what I thought he needed to do .
I had to take many months off work and have proper therapy. DH also came along and had therapy with me. We are now very happy (well fingers crossed but I believe so.) We went through a hard time but the truth is we both wanted to be married to each other.
I am not saying that everyone can do this, but I just wanted to post something which says troubles in marriages can be surmounted. Obviously only if you both have the will and energy to do so.
Not sure why I have posted this but I think that in my case one example of extra-marital sex did not end things. I can understand why some people would think it would. And that's everyone's choice. For us , one aberration does not negate the relationship we have had and have now and still will. As the person who had the affair however, it is hard work to get back from that , so for those whose OHs are the one's who have done that , don't let them off the hard yards. It takes work.
I really am not sure why I have posted this but I think it is just my experience in that an affair does not need to be the end of the road if you can address it together and both of you want it to work. If both people don't then yes , it will not work but I hope I can give some encouragement for those who want to work through it.
Obviously prepared to be flamed but I am truly just posting this to say sometimes it is possible to work through things and be happy.
As I named changed to - I am probably going to regret this .
