Congratulations! I am so happy for you OH, you've got a plan. You've also got a husband and that makes all the difference as I see it. All my friends are married and/or still working, so no one to play with during the day and evening. . I am anything but a TV fan and sure don't want to sit at the computer all day. I did that a few days, but I began to feel so worthless, but that's just me. I enjoy getting out and about and in living alone, I crave the interaction with people.
And every time I left my house, I was spending money. It's important to me to have some sense of accomplishment, whatever it may be...so that's why after a year I went back to work part time. It won't be that way for you, with the d/h around and will be fun. Being single and retired (without a lot of money to travel) is a whole different can of worms.
I too am alone, and I admit to having some money, but not oodles!
I attend a yoga class, go out with a widowed friend once a week, and go out to eat with close friends once a week.
I am lonely, but I talk to my cats, and when the weather improves, will start doing something/anything to my garden!
I ended up hating my job, so this is better; and I spend far too much time on here!
