Married to A Pastor With ADHD

I am married to a pastor with ADHD. We have been married for 5 years. I went through the courting stage where he was hyper focused on me and his focus has been on anything but me since marriage. He has 4 grown children form a previous marriage that I love. These children however have been allowed to take advantage of me on several occasions, financially, emotionally, physically. it has taken various discussions to have any changes made. I am an outgoing person that loves the Lord and because of my commitment I honor my marriage although I am extremely unhappy. It is unusually difficult because he counsels others when needed but seems to have difficulty with me. i would just like to talk occasionally and be heard. This morning he told me his sermon and I listened while he talked for 20 minutes when I responded with some thought on my own he didnt acknowledge my comments and changed the subject back to him as though I didnt exist. It is a lonely existence. I am so thankful I found this forum because I cannot share anywhere else and fell extremely alone. This site has helped with these issues.
