So you were going out for beers several times a week to let off some steam while your wife is at home taking care of your new kid. Have you ever afforded her the same luxury, a night out with the girls or just sometime for her to be alone and do her while you take care of the kid? Was it as often as you went for beers? Maybe the reason that you felt compelled to lie about this is because you felt guilty for doing it. Not just the lying, but you taking time for yourself and just being all out selfish.

Hey, I get that life can be complex and stressful, especially with a little one at home. We all need some downtime now and again to recharge. But it sounds to me like you were going to that well quite a bit. She gave you several chances to be honest and you just couldn't do it. Now you're upset because she told you she didn't want to track you, but you find out that she is? Really? She's not allowed to change her mind? Afterall, you promised twice to not lie to her about going out for beers, but apparently you changed your mind about that too. Is she not allowed to be upset about that?

At this point, I think that counseling would do you both some good to help restore the trust and identify what the priorities should be in your marriage.
