Why would he want to chose? If he can have you both and fulfil both aspects of who he is in those different relationships. Give it some time and the shiny newness of it all will wear off and then reality will set in. Relationships go through cycles, there will be times when he will crave your company and times where he will crave hers. It doesn't make either relationship better or worse, just different.
Derby's hit the key here. Lots of wisdom rolled up here
We're talking about something similar in another thread. Brains require variation in stimulation to stay healthy. Not 'more or less' - just different/varied.
It's all good.
