I’m not allowed to be anything but happy

My husband and I have have many rocks in our marriage. However lately as we approach our 3 year wedding mark we can’t seem to get along or see eye to eye. Putting a toll on not only us but this marriage of ours... He works part time at our local target as a hardline associate and I work at a nursing home full time. We both work very hard and are tired at the end of the day. I have a set schedule he on the other hand works all kinds of hours. Working at a nursing home is very draining both mentally and physically. We have had issues since about March. Dealing with work and the issues with in our marriage, I am exhausted at the end of everyday. He doesn’t understand or seem to understand what dealing with all of this does me and my body. I’ve been mentally exhausted for weeks now. Instead of him trying to understand and ask why I’m exhausted or what’s wrong with me. He states I’m always tired and it’s nothing new. Don’t matter how many times we have talked about our issues and I’ve tried to explain to him how I feel he either doesn’t care or doesn’t understand. For months I have begged to him to understand and to forgive me for being so tired all the time. Each time he says sorry and that he understands completely. But eventually makes comments to me like the one above. I just don’t know where to run too or what to do. I don’t talk to anyone , bc I don’t like people knowing my issues within our marriage. I’ve tried to suggest couples counseling and he shut me before i could finish my sentence. Glow is the only support I have. Thank you all for reading. Have a blessed day ❤️
