Well, I could have written nearly all of your post. I don't really have any wise words as I am in a similar position and don't know what to do either, but I just wanted to say you are not alone.
He seems to have no idea how I feel even though I've brought it up a few times. He's in his own world when it comes to feelings and relationships. I don't think we are compatible any more. I don't think we're meant to be together. But I also feel guilty for being in this frame of mind.
I especially relate to the above.
Just a few random thoughts, since I can't help with what you should do:
I have been married over 20 years and have noticed that my feelings for dh do tend to go in cycles. Right now, I don't like him very much and can't see how this situation will change, but I know I have felt this way before and the feelings did change, so I feel, on balance, it is better to sit this out and see what happens than do something drastic I might regret ie break up the relationship. Do you feel that way, at all?
I would also say that if your dd is only 5 year old, that is a very trying time in your life. There are lots of demands on you, physically, emotionally, which can have a negative effect on your marriage. But obviously, she won't stay 5 forever, and as she becomes more independent you may find you have time and energy to devote to your relationship.
Also, the dynamics within the family change. Right now, your dh is playing good cop to your bad cop, but in time, your dd may relate more positively to you as you can do 'mother and daughter' stuff together. I have a daughter who is 15 and there have definitely been years when she has related more to me than to her dad, though I have to admit now she is much more a Daddy's girl - I am seen as the Enemy - and that is one of many strains on our relationship right now.
Finally, I wondered if you were doing anything for yourself? Do you work doing something you enjoy, or see friends, or pursue a hobby? These things might not directly help your relationship with your dh, but I find they are the little things that keep me feeling a sense of self-worth.
