Hi, I'd like to help you with your question.
It sounds like there is communication going on between the two of you, but the messages getting across are damaging and not beneficial to the two of you.
From what you said, your husband is a very straight forward type of personality. Logical and to the point, from what I understand. You, on the other hand, feel you are more emotional and that part of this is from your experience staying home with your son, creating a different perspective for you.
Both of you would benefit from moving closer to one another in your communication styles. Understanding one another and being more empathic towards each other would go a long way to help you both communicate better.
There are some great resources that can help. One is called The Five Languages of Love. You can find it on line at http://www.5lovelanguages.com/. It is a program that helps you learn the communication style of your partner and how to better understand each other.
You also need to talk with a therapist. Talk with your doctor about a referral or if you attend church, your pastor can help. Pastors are often good marital therapists or they know of good therapist because of the number of marital issues they deal with on a day to day basis. Also, you can search on line at http://therapists.psychologytoday.com/rms/ and http://www.find-a-therapist.com/. There is also a good site on how to find a good therapist at http://www.webmd.com/anxiety-panic/guide/how-to-find-therapist.
There are also some great books to help get you started. One is called Communication: Key to Your Marriage: A Practical Guide to Creating a Happy, Fulfilling Relationship by H. Norman Wright. Another is The Seven Principles for Making Marriage Work: A Practical Guide from the Country's Foremost Relationship Expert by John M. Gottman and Nan Silver. You can find these on Amazon.com or your local library may have them available.
I hope this has helped you,
