Looking for support going through separation/divorce

Hello everyone! Thank you for taking the time to read this message. I'm new to this site and I found it online looking for online support groups for people going through a divorce or seperation. I've been married for five years and my husband and I are currently seperated and speaking of a divorce. Things have been mentally quite tough for me the past few months especially now during covid19. He's never physically cheated on me, but I caught him speaking to a woman online whom I had believed was his online friend all these years because she was also my online friend as well which I met through him. In late Jan I had seen that they were talking on the phone etc. behind my back and my husband suddenly didn't appreciate me going through his phone. He decided to move out a few days later and stay with his mom and we haven't been together since. We are cordial but things got ugly before they got cordial. The worst thing is that this woman doesn't even live in the same state as we do and she's not nearly as attractive as I am. I know looks aren't everything, but I've been through so much things with this man I've been there for him through thick and thin and then he just ups and leaves me just like that. He opened another bank account on me a few days later, stopped picking me up from work. Idk things are just so confusing and that has obviously left me very vulnerable needing and wanted to feel wanted by another man. In which my ex's were happy to hear that I'm going through a divorce and want a second chance with me etc. I know I shouldn't date while legally married and were in covid19 I can't date anyway. But I must say that sometimes things get really tough for me and I emotionally shut down completely. I had started breaking out in hives on my body which has never happened to me before and I had grown two white hairs. I've just been going through it, so if anyone has any advice I would greatly appreciate it. Friends say that I should use this time to get to know myself and be happy with just myself, I do love myself however I am only human and it's natural for me to want to try to move on from this rough time in my life by any means necessary. I'm just very stressed lately sorry to vent almost my whole life to you guys lol. Have a wonderful night/day!
