> She says she wants me to be happy, that I'm a great husband and if this is what I need to do she understands.

If she's really understanding about separation (but presumably also wants to be with you), she will also be understanding about managing your time spent on work or with her.

Figure out how to manage this and still be a good husband.

> Married for over 10 years. ... we do care full-time for 2 kids. My wife and I get along great. I love her. We have fun together.

Don't leave the most important person in your life just because you want to lock yourself away for days and work.

Stay together.

Agreed. This would be a different story if she was making you choose between work and love, but she sounds supportive. I highly doubt any project is worth rushing to extreme lifestyle changes, killing relationships with no known gain.

Work with her, try to get what you both need. Communicate.
