This is something I've been personally working through for the past couple of years, maybe one or two more.

For the original poster, opening up to your husband, and not putting on that happy face((not to swing the pendulum too far the other way, if that makes sense)), can help strengthen that bond between you, as you allow yourself to be vulnerable to him.

In regards to what I am learning, is that how can I strengthen and develop friendships, etc, if I am unwilling to share the not so good, along with the good moments? Must have been back in '09 when I joined fb, and found some old hs friends/classmates. Well, er, um, a couple of these people were less than enthusiastic to reacquaint with me. And one word that came to the forefront was 'fake.' I was in therapy, at the time, anyways.
Fake? My half sister who is 16 years younger than me, and we are far from close and connected called me 'fake', too.
What makes a person 'fake', I really had to wonder. It's not as if, I am not an honest person. And it's not that.

Someone new, started working at my last job site. And it was like a light bulb went off in my head over what does 'fake' mean? Smiling and everything is alright, actually was rubbing people wrong this whole entire time, in my life.
What is that catch-phrase for when MTV put out 'The Real World'? 'When people stop being nice, and start getting real.'
By this point, on the job, thanks to working with the individuals that I work with, finding myself having experienced some major life changing events on top of this job. I 'get' it!
If all I do is smile, and say it's OK. How can anyone know what I really need, want am feeling, etc? It's a fast pace I work at, and most times, niceties need to fly out the window, but in a respectful manner. Which means, got to get into the figurative 'trenches' with these people that I work with and in doing so, a bond forms. And I've learned and grown with the people I have worked with, and those that I work with now.
No time, to stuff emotions, but also no time to have cat fights either, so to speak.
In many ways, my place of employment, over the past three years, has had a tremendous therapeutic effect, and learning what putting on a fake happy face can do and how taking it off can be beneficial and how to take it off, appropriately, the lesson has been priceless.

Hope you can open up to your husband

I was trained the same...smile, etc..
