Hi Kieran. Welcome to the club. The club we all want to get out of! I don't want to be redundant to those who read a lot of the replies, but I'm gonna give you a simplified version of a way my wife and I have figured out to help me get myself under control. I've been at it for 30+ years and want to get the heck out of this club too. Here it is, 5 daily steps to do on your own or with your significant other;
1-Pray morning and night.
2-read scriptures every day.
3-read this blog and post on it every day.
4-exercise.
5-go over the main issue you lie about with your significant other (mine was money)

This is what I do. Read thru many of the replies here on this website and see what others do. There is a lot of good information and ideas from many folks who are struggling with the same thing.

Thanks for your advice, I will take it on board. A lot of what I do is tell little white lies for no reason. Just to make general conversation as I usually don't know what to say, so I just make things up. It has been about more serious things though. Like talking to other people intimately and about gambling.

Big lies are bad, and will cause big problems, but the little lies are bad also, as they form habits, and paint you into a corner that makes big lies come out. Grab it by the throat as fast as you can and squeeze the life out of it.
