Reply to My husband is really negative

My husband is like that and so is his dad. So maybe it is a guy thing? And then my own dad lies a lot for stories and attention. I know my husband exaggerates for attention some time. I don’t really have a solution... just that you’re not alone. I just try my best to ignore it. Hard to ignore though when my husband treats my son like he’s on his deathbed when he is sick with a common cold. Or when my son gets a little sniffly or sunburnt on vacation and he acts like our whole vacation is ruined and wasted. So during these instances I do my best to keep moving forward while making comments like, “oh look, our son is still playing and happy to be out here despite his sniffles! Looks like he will survive and not ruin this vacation! But your negativity is ruining my mood and ruining it for me! If only the dad in this situation would keep it together!” I’ve also sat down with him and talked to him about how his negativity affects and stresses me out. I ask him if he wants me to live another 20+ years and if so, that he needs to find a way to manage this whether it be see a therapist together or he go see one by himself. So far... nothing has changed permanently.. just temporarily every time I blow up or talk to him about it. He also is afraid to turn out like his dad because it also affected him as a kid. Some times I will point out that he is becoming him and he will shape up, temporarily.
