It's good that you don't live together as that REALLY complicates things. if we didn't live together, I would have already left. No kidding.
You need to make some friends and try be independant. My BF and I did break up for 6 months at one point and I felt so good after we went our seperate ways. But we ran into each other one night and both had too many beers and the rest is history...
We did start thinking about this around the same time. You're right. Sheri, you will be ok. It's good that it wasn't a messy break up. Plus, I think breaking up because there's no spark is a prety good reason to end things!
Good luck at your interview. Try to put on a happy face.
