Pb,
I have learned that demanding he change immediately, is probably not a good course of action. I need to have some patience, and approach him in a loving way about this.
It is very wise of you to figure this out. No one can demand that someone else change. If someone is going to make a change in behavior, they have to want to do that for themselves. It's fine for the person wanting to make change to ask for help and patience while making the transition, but changing for someone else's sake, is never going to be permanent or comfortable. You need to imagine how you would feel if he were making such a demand of you. It is not fair or healthy to place those kinds of demands on people we love.
At my age, what I have learned about relationships (many hours of therapy, too) is that we all have our strengths and weaknesses. Finding a partner who can complement those strengths and weaknesses is sometimes the best we can hope for. That they will change to meet our expectations is something I now know is not realistic. If there is a behavior that you cannot live with, save yourself the aggravation and move on to find someone whose behaviors can blend more easily with your own. If your partner meets your expectations in the most important areas, but falls short in the lesser areas, learn to compromise and live with it, as there will never be anyone who perfectly meets your goals for a life companion. Only you can know what those most important characteristics are and how closely your b/f matches up.
I don't know what to say about the vacation situation. I admit that it would bother me too, as I look forward to the vacations with my b/f and the many hours of fun, relaxed, intimate time together we share, that is difficult to have on a day-to-day basis. As a word of caution, I would say that my xh never wanted to go away with me alone as he knew I would have expectations of intimacy and alone time which I know now he dreaded and avoided. I would suggest trying to get to the root of the issue in the most loving and inviting way that you can, so he does not feel threatened or cornered. Maybe the T can help with that.
Hugs,
Brigid
