How do you get over someone you love so much?

Time and lots of it. I find there is really nothing else that does it. Yet still something of it and them will remain.💜
But new experiences and living your passion/a full active life, will help.

No you don't. You are mixing up love with loneliness I believe. He lied and is a cheat so you wouldn't want him if you had him. You would break it off, trust me. Sometimes it hurts to be abandoned or conned, but that is not love. He would never make anyone happy. A good husband doesn't cheat! His wife is probably crying right now. Do you want to be her in 20 years? No You deserve an honest kind person who really loves you and would never lie to you! He did not love you, if he did he wouldn't lie!

Don't give up and get back in the mix date as many as you can it'll take your mind off of it and the right one is still out there. Sand your too good to let one liar take you down. Get back in touch with your best friends. Or make new ones.
This is a lot easier for me to say than for you to do. Lol but my advice may have included one thing that made sense that you could try. It maybe not. If not then you have a really good list of what not to do. I'm like a broken watch I can still tell the right time twice a day.
I believe you know what to do and that's all you got to do is start. Good luck I'm cheering for you. If you need to cuss someone just post who needs a ass kicking and oil raise hand so you can get it out of your system on a safe stranger. Physically I may a little off but just in the head. I'm wishing you the best

Maybe you can love him and not get attached to him. Feel the love between you knowing it’s temporary. When it leaves u will see all u accomplished with the power of your love. Just remember as badly as u care for him he’s married so just don’t cross the line. Tell him not to too and maybe u can still stay friends. Sometimes I wonder if when that happens to people its like a connection to a past love. Or a past life where u had that type of love. Like the connection and bod aspect of the connection stands out in your current life and reminds you of how deeply you lived before with some one.

Cry, reflect, find something enjoyable alone, don't look for love as that's when you can make mistakes

It will take awhile. You may need to get another date with someone else. Or find a new hobby. Or go buy something really nice that you like a lot. Or just time. But these things can help

sometimes god or fate or something else makes the decision for you...

The best way to get over a man is to get under a new one. 🤪
