And let me add another point here to McGraw's notes above :

The questions above apply to starting a new relationship too...

If you aren't ready to divorce, you certainly aren't ready to "date"...

Yes, I am making that point specifically for you...

But the stuff above is good for getting involved elsewhere as well.. a lot of it still applies

If you have unfinished business at home for example, you have NO BUSINESS getting romantically involved elsewhere
