Ok, without repeating my whole soppy story... I am married, having issues with wife, ended up getting involved with an OW. Now that things are serious and divorce is a reality, I have realised that I can't go through with it. I love my wife, and don't want to give up our life that we spent 12 years building. Problem is... I have tried to break it off with the OW a few times, and it just never works. By now I have also hurt her very badly, but for some reason she keeps taking me back. I choose my family, and will do anything to make things work.

How do I break things off with the OW? I am a dog for what I've done, and I know that very well. She has been through a lot in her life, and I promised that I wouldn't hurt her. I will now be going back on everything I promised to someone who trusted me. I know that it's exactly what I would have done to my wife, but I have been going through a lot of confusion and my bipolar has been going haywire.

Please can anybody give me advice?
