Well, having been MARRIED to one of those super allergic types....for almost 35 years....I can say that it does not go away, the shots never helped in our case at least. I still have my horses, had them at my house even for several years, just built it with what he affectionately called a "decontamination room" that I had to go in before I could step foot in the house......strip my clothes off, put them immediately in the washer, shower. Just a part of life, if I want to have horses. He also cannot EVER sit in my truck, neither can our son, who got hubbys "good genes"....lol Sadly many allergies get worse with more exposure, in fact.
Not worth an ER visit (once was in ICU on a vent when he tried to stay at his friends house overnight-they have horses), so I do what I have to. Our MD kiddingly says I am trying to kill hubby with my hobbies. Lol. Neighbors see me a lot in my undies-I figure from a distance it is no different than a bathingsuit-just a little stange in January.
Sad part is-hubby LOVES animals and they love him. When we have them at the house they knew when he got home, ran to the fence and he gave them a carrot-then immediately in to wash hands and face.
You are very right tho, it does have its positive sides-he has NO CLUE how many "clothes" my horses have, how many saddles I have.....for only one butt!..HAHA! He just shakes his head when packages arrive anymore-he has stopped asking.
