Do you think it's bad if I tell my wife little white lies all the time?
I think it is, why do you tell her so many little white lies?
I like to make things up to spice our relationship up a little bit.
When you are in a relationship as significant as marriage, you should always be truthful with your spouse. You may not think that it matters if you lie to your spouse but it is actually wrong since it can cause your spouse to distrust what you say and your relationship will suffer. For the sake of your marriage honesty is the best policy.
I think it's fine to tell them, she still trusts me.
You should really be honest with your wife. If she finds out about this, she may really question your relationship and it would hurt her feelings to know that you've lied to her so much. Don't risk your marriage over something like this.
