I would decide one way or another so you're not working at cross purposes to yourself and cause yourself problems down the road.

In any event, you need to be able to support yourself and your children. If you need school to do that, then ignore the men and meeting other people, concentrate on getting through school and getting a good job.

Then you can work harder on the marriage and stay together or separate and go on to the "next" step. But without a "plan" it will just end up being an emotional, financial, confusing mess I think.
