What level of wrong is this. Does it even matter?

You obviously already feel like it's wrong or you wouldn't be asking this question. You are still married. You made vows to your wife that you would remain faithful and love, honor and cherish her for better or for WORSE. OK, you've got the worse part and now you are bailing. I understand that you are lonely and are not getting your needs met in the marriage, but as long as you are in it, you are in it. You have children to consider too. My suggestion to you is that you try to find some other way to get your needs met that do not require you to break your vows and will not set a terrible example for your children if they ever find this out...and believe me, they WILL find it out. Kids always do. Spend time at your church working on charity committees, or join some of the men's clubs. If you are not a church member, join a bowling league, a card club, or something like that. This will give you some fun, innocent time away from your spouse, doing something just for you. You can also take a cl at your local Jr. College. They have all kinds of community cles in everything from pottery making to Anthropology. You will broaden your mind, meet new people, and set a good example for your kids. Meanwhile, make a time-line for getting your finances in order, and getting that divorce. When you have filed for divorce, and ONLY after you have filed for divorce, you can start looking for new female companionship. If you do things the right way, you will be able to get up in the mornings and look in the mirror and see a guy you like staring back at you. Good luck.
