You know, I'm kinda leaning more towards what Dagny had to say here. I don't think that you really need his "permission", so to speak, although I can understand why you might want to let him know.
If you really DO need to let him know, probably just the first two sentences that you wrote might be sufficient. Anything beyond that kind of sounds like you may be trying to elicit some kind of response from him about either how happy he is that you're doing this, or how pissed he is that you're doing this.
Either way, this is something that you are doing for YOU, right?!
I'm not sure. I'll be interested to read other's thoughts on this!!
