I really really understand about school being on your mind 24/7. However, the objective fact is, it shouldn't be. The objective fact is, you should be happy with a 3.8 .It is better to settle for a less than perfect grade, than to settle for less than perfect marital or paternal/child relationships.
The problem is, if one has Aspie obsessiveness, it is extremely hard to think about other things; it is extremely hard to be happy with that 3.8. even if you realize you should think about other things, even if you realize you should "settle," even if you want to think about other things. Believe me, I know.
By the way, sorry about your dad not understanding. Realizing about Aspiness in myself was a huge thing. My life hasn't been the same. (which is good) But people who haven't gone through it don't understand. My best friend had an amazing reaction. Then he told me, he suspected the same thing about himself. I stopped telling people other than him, because, at best, it meant nothing to them.
The success of your family depends more on the attention you give your family members than on your academic success.
In reality, a job does not always depend on the perfection of your grades (a tough lesson some of us learn when we get into the "real world") (side note, every wonder why the word "real" is usually used just in reference to unpleasant things?)
Many men make the mistake of thinking that providing for their family (which
is necessary, obviously) makes up for emotional absence.
However, I know that you don't want to be emotionally absent. i know you don't want to get away from your family. Please don't take my previous words as being harsh or non-understanding. The real problem has to do with the difficulty of focusing on different things at once. This is especially hard for us with AS, with our obsessive nature. I wish there was some amazing advice i could give such as "do a and c and then you will be able to study at times and then at other times turn your full attention to your family." Not that easy.
Our studying/analyzing/obsessing brain does not come with some sort of on/off switch. :help: It would be great if it did. (freedom!):bounce: :cloud9: Our mind can itself entrap us :banghead:
So I haven't given you a remedy. Just a bunch of smiley faces. (weird humor)
However...
My greatest obsession in the end was a person. Your wife can be yours. (it'd be cool to find the on switch for that

:cloud9
Now I'm making it sound like "it's all your fault." I don't mean that. sorry.
In all honesty, I'd be so amazed if a guy i cared for liked me enough to marry me, that i'd let him have all the few-week-period-to-figure-things-out that he needed. Have things been difficult between you and your wife for a while? Or is it only in these past few weeks since you've been figuring things out? That could be an important question (you don't have to tell
us unless you want to.)
