I don't know what to do anymore

I have been married for six years, we have two children together and I have one from a precious relationship. The problem is we have huge communication problems. When he gets mad he ahuta down, and when I get mad I get very angry and yell. Im better than i uaes to be, im working on my problem. When we are both mad the more I talk and yell the longer he stays shut down. Ignoring me for a week at a time! And the longer he ignores me the more upset I get. How can I get him to just talk to me when he's upset? To open up to me?
To be honest, our relationship is teetering on the edge. I don't know how much longer I've got to try to resolve our problems.
He doesn't appreciate what I do, he only focuses on what I'm not doing and complains about it all the time. While, at the same time doing the same types of things he's complaining about.
I feel like I have to be perfect to please him. He is always upset lately, nothing I say or do changes it.
He goes out all the time and never wants to spend any time with me. He always wants go hang out with his friends a d go to the club. We used to do a lot together, now I can barely get him to sit in the same room as me for more than an hour. And forget about going out together, I practically had to force him last time. We have our good times, but they are becoming fewer and farther between.
There are no I fedelity issues, just an inability to communicate properly, a lack of understanding of each others wants and needs, his seemingly inability to comprimise, and a lot of hurt feelings.
HELP! What can I do. I really truly love him and want us to be happy together for many years to come. What can I do?

After reading your post I can only think of two words that may help. MARRIAGE COUNSELING.
Hopefully your husband will see the need and decide our marriage is worth saving.
It is the only way I can see to work on your communication, It can be very helpful to have a professional outsider listen to both of you. This person would be able to help you talk about thoughts and feelings without yelling or being mad.
It is I feel, your best chance.
Good Luck
