I find myself in the same conundrum at nearly 50. It's hard, but you can now focus on yourself and what YOU need.
Try MeetUps (not dating), resurrect old hobbies, get a gym membership, go back to school, or volunteer... whatever helps you get out, get your mind focused on YOU and YOUR future.
Socialize in a safe way that'll expand your contacts. Hopefully you'll meet people of like mind, & make some friends quickly.
Also look into IC (counseling), or a Divorce Support group. Those'll help you process this trauma. Leaning on supportive, loving friends and family can help, too.
Don't play 'pick me' with your WH. I did that, and it was/is humiliating. He's not going to have some giant epiphany/ come back/ be the perfect husband suddenly, like we hope. (No matter how much sense you try to talk into him)...
I really am sorry you're dealing with this. It's a long, hard road with many ups and downs.
Stay strong, be brave. You'll be ok in the end! I know that's little solace now, but it's true.
Others will be along with more detailed advice soon!! I just saw your post and thought I'd answer, so you know you've been heard.
Hugs!
