Wise words from Sourgirl.
The other thing to consider is that it's ok (as painful as at may be) to admit that you are not compatible with someone in the role that you currently hold. And the truth is, that if you aren't, you should let go and save yourself more misery. You may very well be able to find common ground but if it's just like slogging through mud all the time, for a long time. It may be something that just won't work. I think we know deep down inside when that happens. Whether or not we can admit it.
