Yes, most marriages go through periods where both partners are way stressed, sometimes over the same issues, sometimes over separate issues.
Parental influence is always a challenge, and it sounds like there are cultural pressures there, too. I ended up breaking most ties with my mother, as her influence was like acid in me and my relationship. As Rhonda said, you and your husband are the main unit now...not family, no matter how supportive they might or might not be. You're an adult; you have to make decisions that well benefit your family unit (you, spouse), and indeed they may not include the family right now.
Men are indeed like that. Now you know. Sometimes it's better to just let it go, and eventually they'll get around to tell you what's bugging them. Nagging only leads to confrontations that aren't pleasant for anyone.
My husband and I committed to the institution of marriage, when we said "I do", 38 years ago. That is to say, we sometimes don't like each other, we sometimes yell at each other, or stop talking altogether. And there are times when we've privately wished the other person would "just go away!!" But we've always LOVED each other, and each have made the commitment to weather these small storms -- that seemed enormous when they were happening, but over 38 years, have been small indeed.
Hang in there. Keep the parents out of it. Love your husband, and be there for him, even while you need him there for you. It is stressful to be sure, but if you're committed to the relationship, it will stand the strain.
(And I know it's hard to believe, but people can go for months, even years, without sex...and still love each other, still be committed to each other, still stay in a relationship.... Sex is nice, but commitment and acceptance and tolerance are even better.)
