Yes it's unrealistic for this (particular guy). It's not who (he) is or what he is about. When you come to the realization that the person you are with can't or won't give you what you want then you have a decision to make.
There are only two ways to experience joy and peace of mind in a relationship. We either get what we want or we learn to be happy with what we have.
If you reach the conclusion that you can't deal with the status quo then you should probably move on. People change when (they) want to change. Trying to get someone to behave differently usually leads to frustration on our part and resentment on our mate's part. What doesn't work for (you) may be fine for another woman. This is not about "right" or "wrong" but rather about "agree" or "disagree". In order to have a successful relationship (both people) have to want the same things for the relationship!
Generally speaking there are two reasons why someone in a relationship with you would not give you what you asked for. 1. They don't have it to give. 2. They don't believe you are worth the effort to give it to. Either way if you decide this is a "deal breaker" or something you don't want to do without then he is the wrong guy for you. Best of luck!
