Excellent, Edwin! Stay with it - as it will get easier with time and distance.
I was 50 when my LE began, albeit married for 25 years, so it was a perfect storm waiting to happen.
Hopefully, the self care that you have been doing as a result of this will continue.
Although, it's not really about being attractive to someone else or presenting ourselves in such a way to meet that goal. Rather, it's more about the attractiveness of our inner world, how much we love ourselves, and how we take care of our own needs first. This will then radiate to our outer world.
The validation and attention that we seek from others so that we feel "good enough" and valuable is really not necessary, as we literally have all of this within.
Best to you!
Never give up! Keep moving forward, no matter what.
