I really feel for you and understand some of what you're going through with your H.
You both are living in separate homes. H has a lot going on. The OW and a gf? What about you?
Your own words, "I know I can find someone else if I want. I'm a nice and attractive person who gives a lot to others and puts great effort into the relationships I build. I am also not afraid of being alone". Don't wait around for someone else to make you happy or to give you what you deserve. I totally get that you want to work things out, you have many years of happiness, etc etc.. that is what you'd like to do, but right now, work on you.
What do you want for yourself? Take H out of the picture for a second. What brings you joy? Is there something you've always wanted to do? Or somewhere you've always wanted to go? GO FOR IT GIRL! Don't wait around.
If things are meant to work out, they will. For now, focus on YOU.
Here's a challenge for you: Do something that scares you. I'm looking forward to seeing what it is. Want to know what scares me? Cooking is one of them...lol... It's something I really need to improve on. Any recipes for beginners are welcome
