@Jenny, You have a beautiful Dad that I wouldn't doubt everyone would love to have! Congratulations! Always good to hear great outcomes that make us feel good & have Happy tears in our eyes. Probably proud hugs between both of you next time you get together. I didn't have to worry about telling my parents as they passed about 10 years (early 90's) before I began my road to discovery of me being trans, so late in my life. I have about a dozen people I have come out to starting at cd & my journey to trans, telling my Sis, her husband, her two kids & their SO's, a cousin & his wife plus my closest friends, it has all been good & they are supportive. When you give love you get love.
Happy for you!
Jamie
