Just like other posters my Husband and I went through this as well. Though, I have a little different take. First good for you for recognizing the need to ask for advice before the resentment builds.
Second, with regards to your feeling that he looks at you differently, is it really him who sees you this way or you? It sounds awful, but I realized when I had those feelings it was about my own sense of value in the home. We had always contributed 50/50 financially and all of a sudden I no longer had that security. I was feeling as though I was now totally dependent on him for all financial needs which for me was really unsettling. One day I finally broke down into tears asking for money to buy new clothes and we finally talked about how I was feeling, though I made sure not use the word "you" or tell him that "he made me feel x", and to focus more on why I was responsible for these feelings I was having. His response was amazing. This conversation brought out why and how much he values my "job" in our home, and how he works so much because he sees my value. Around this time we decided to take time for us, and began our "date night" bi-weekly with our son going to grandma's. Currently Im pregnant so we upped date night to weekly because we both know that it will be a while once the new baby is born for me to be comfortable leaving her. All of a sudden he also realized that I don't get to leave work at the end of the day, and that cleaning up all of his messes and not having his help when he is home was really making my job harder. While I understand that it was my choice to be a homemaker, he needs to still be a father and husband when he is home. So we discussed what his "chores" at home are so that I feel ike he is also contributing and I don't have to ask him to do stuff and feel like Im nagging him. He takes out the garbage for me, and carries the laundry downstairs and upstairs for me. I only ever ask him once to do anything around the house and give him a timeline when I need it done. It almost always gets done on time now. but he let me know that when I repeat my requests I nag. Now I know I expect very little of him with regard to helping out at home, but Im never disappointed, and he is doing more and more and our relationship is getting better and better. Every night after dinner, he takes the baby for father son time while I do the dishes. Weekend's are tough, but at least my husbands hours are not so long and we all get more time to spend as a family.
Third, with regards to helping out with the baby, many men look at new babies as "mom's job" and can't really connect in their heads as to how to bond with them till they are bigger and able to play. This is not to say that they don't love them just as much, some just can't get that nurturing thing down. It used to drive me crazy that when my husband took the baby, he would place the kid in the swing and get on the computer. Asking him to do stuff for the baby to help me was like pulling teeth and he seemed bored everytime I asked him to hold him. There was no doubt in my mind that he loved our son, but he just didn't know how to interact with him. I would give suggestions, and lists of things to do, but nothing seemed to help, till all of a sudden our son was mobile, and could pick up and recognize toys. Now I can't tear the two of them apart once my husband gets home. They spend the entire evening playing, and even when hubby is on the computer relaxing our son is climbing on his lap and wanting to do everything with Daddy. These things just seem to work themselves out.
Becoming parents is no easy task, and learning how to do it together is even harder. Lots of communication, less blame, and removing the "parental competition" ("I do x more than you" stuff) is what solidifies and enriches the transition. Learning those cues is the hard part. It takes time to get comfortable in your new roles, just remember that you love him, and that it will get better.
