Lena, I can understand your situation and I empathise greatly with your concerns of being disloyal.
I too supported my husband throughout his career and put him first in everything I did. I moved house many times and I don't have any particular friends either.
I wish I had some helpful advice for you but instead I just wanted you to know I can relate to your situation. Because I have mostly capitulated throughout 24 years of marriage I think my DH would find it almost impossible to adapt to my change in needs so I can also see it from your DH's point of view.
Keep talking here, these ladies are a lifeline for me.
