You are very kind. I feel sorry about your foot. I used to play soccer and believe me, I used to fight against bigger guys for the ball and never got injured. One day, as the enemy kicked the ball into our own penalty area, they caught me too far away from it. Knowing myself I ran backwards, feeling cocky you know, and I bent my left foot. I had to take some shots to fix it. It hurt big time, and so my dignity, hurting myself. Your tendon will get better with the passing of time, just don't disobey the order or you will get worse.
When it comes to your husband, love him while he remembers you if the Alzheimer's come to be the guilty party. Then you will need to love another guy, the one that comes and goes like a lover. You will be split into the old lover and the new one.
We had at home our own Alzheimer's case, but it wasn't one, something similar. We loved this old lady, my mother in law, gave her all the respect and care, only to be treated back like garbage. Believe me, there's so much you can stand, like watching her at midnight, stepping on a chair, step on the counter, grab 2 glasses, one on each hand, slide slowly to kneel over the counter, step on the chair while holding both glasses with both hands and never, ever put the glasses on the counter to be careful. She did that a few times while I was watching her, right in the middle of the night! Had she fallen, and died....we would be paying for her funeral or care!
Finally, love was broken, she had to go, unfortunately she went back to Guatemala only to die due to her own negligence 6 months later. I know, I feel guilty, but things happen for a reason and you can't force the outcome of an event when the other party wants different result.
Yes, travel, spend some dough to have some fun. As I said, I hope whatever your husband has it is not the beginning of Alzheimer, but in case, cherish him while he is who he is and who you loved, because the future guy may not even want to be with you because he will think you are a stranger. I hope that wasn't too hard on you.
May peace be with you.
