I have/do, once a week each. The arrangement will end soon as I am temporarily going to be working elsewhere for my job for a few months. When I come back, I might see both again. I pay out of pocket, and they're both expensive, so it would probably go biweekly instead of weekly.
I find them both helpful in very different ways. No. 2 is more practical stuff. No. 1 is more emotional stuff. No. 1 does annoy the heck out of me at times, probably because of the emotional stuff, but I think I'd miss the aggravation.
I don't see any issue with seeing a second therapist for a few weeks if it would help with this one issue and soothe a rift between you and your main therapist.
