AITAH for telling my situation-ship that i refuse to date him if he has bad handwriting.

I 27F and the person I'm in a situation-ship with 26M had an argument where I've explained to him that it upset me that he left it up to me to finish and put through an application for something he started. He couldn't finish the application in his name so I said 'oh that's no problem, just put it in my name and you can just use my address its fine' I was very busy working that week and just thought it would be simple enough to use my details.

He started saying throughout the week he didn't really want to do it because he had to physically write my name on the document and as I was too busy really to think about it, it sorta just kept getting brushed off and pushed back. Eventually he went back home and had left this application for me do to do (it wasn't a long thing by any means it took 5 mins to do) because he said he is 'Insecure' about his hand writing and worried that people wont understand his letters. There were some further concerns about it having to be sent from my email and so on but realistically it was easily solved by just using my computer and logging onto my email.

I don't know if I'm crazy but it just seemed like such a silly thing to say that he couldn't write my name (my name is 12 letters long) clearly enough for a application that it just felt like a lie or an excuse.

I told him when we discussed it later that I truly can not imagine a life with a man, marriage, children and many decades together with a man who is so insecure about his handwriting. I gave examples of family planners/calendars being illegible, forms needing to be written in emergencies in hospitals. Or even as simple as always having to write Christmas/birthday/get well soon cards all having to fall on me because he's not willing to work on his handwriting. I told him this was something i was unwilling to accept and he laughed and thought i was joking.

I am crazy for thinking this is not something I want to deal with for the rest of my life?
