This is a particularly difficult situation since you can feel that you are on the cusp of a change.
Perhaps the best way to approach this is to recognize that fact: Something has to change. It is no longer viable to continue in the relationship you are in the way you are in it.
At this stage of the situation we know that you are not satisfied with in the relationship you are in, otherwise you would not need so much fulfillment. The man you are looking to spend more of your time with sounds much closer to someone who fills you up. Time with your boyfriend sounds depleting, demeaning and unfulfilling. The money and the looks are temptations, but how you feel when you are with him is better than a gorgeous bank account that leaves you emotionally bankrupt.
I would encourage you to be as honest with your boyfriend as you are with the new person. Tell your boyfriend that you feel less attracted to him because of how he treats you, and feel better when you are around other people. Let him deal with the fact that he is not in the relationship the way you would like. Honesty allows the truth to be used as a vehicle for change. Either he can make the shift toward improving the relationship with you, or you can make the decision that it is time to move on.
