Marriage is not easy

It seems like the best advice for newlyweds is to tell them to be patient. That’s all I keep hearing from people as if they somehow know that’s something I need to hear. I never felt so vulnerable, confused, out of my element, happy, unhappy. I feel like I’m rollercoaster with so many mixed emotions. I’m struggling with dealing with his attitude or personality I don’t know which one is it is anymore. I feel like I have to deal with smart ass comments or bitchiness on day to day basis, which causes me to shut down. I’m starting to notice how uncompromising he is. If I let him know what bothers me, I feel like he gets defensive and tells me how unhappy he is and how I don’t live up to his expectations, which I find very vague because he never clarifies. Or he says he’s working on it, and I may be too sensitive. We definitely have communication issues. I feel like I’m starting to have intimacy issues as well. I don’t really trust him anymore because of how nasty our fights get, yet I’m so attached to him and our relationship. I’ve been disappointed so many times but I really don’t want to give up because It’s not all that bad. I once was super happy, it was almost too good to be true but I guess that’s just the honeymoon phase. I hope this is a phase as well.
