Feeling neglected and put down.

My husband and I have been married for six months.  We were together for 5 yrs and engaged two of those years. I did notice signs of ADHD while dating, but it wasn't constant.  Since being married my husband is constantly distracted.  I can never seem to have him focus on me/on our relationship.  I constantly feel like I am put on the backburner and that everyone and everything else is more important than I am.  I cry often, because I miss my husband and want to see that I am important to him.  He is genuinely sorry and does his best to fix things, but that is just for the moment.  As soon as I think things are getting worked out and I smile, I am just ignored all over again.  Also, I am constantly 2nd guessed on everything I say, suggest, or do.  I feel like (in his eyes) I can not do and say anything right.  I am constantly corrected and my sentences are rephrased by him.  I feel like he is so selfish while I am mostly selfless. I often hear about his wants and I always give in with a smile on my face and in my heart.  I never hear him care or suggest things that would make me happy.  When we finally do things that make me happy, he seems disinterested and/or crabby about it.  The combination of these actions has worn me out. I feel like my shine is gone.  I am no longer happy.  It has been along time since I have felt happy.  I cry often, I have put on weight since, and I feel so lonely and neglected.  I know he loves me and he hates how I am feeling, but the more we try the more hurt I become.  He was diagnosed with ADHD as a child.  I think it is the cause for our marriage being where it is at today.  I do not want to give up on us and I will not.  I need some advice/tools as soon as possible.  I can not take another day feeling like this.  I feel everyday is taking a bigger toll on our marriage.  If anyone could offer any advice to us, I would greatly appreciate it!!! We are planning for a family and I refuse to bring a baby into a place where I am sad and confused.
