For my future partner I want to become a muse, who will inspire him and give him power when he feels exhausted.

No secrets and no mysteries - the both things never help to make relationship stronger, so complete openness is the first thing I promise my chosen one.
Are you curious what the second is?
Then we need to start a conversation!

I want to find a kind and simple man who knows that it's very easy to keep smile on his woman's face... and who will be ready to fulfill this task for me.

Happiness means something different for everyone. But when two people realize that they find joy in the same, they are an ideal couple.
Perhaps this is the best description of what I'm searching for.
