If he respects you he will not go, period!
He should be an EX before you are divorced running with kids. In a broken marriage, he’s absolutely nowhere near ready for you, drop him like it’s hot, before your sorry, to me read back what you wrote, you answered your own questions. Disappear from his life he won’t be so disrespectful to the next lady. Best wishes 
Find new boyfriend. ASAP
It is cheating. You need to get rid of him. If being in an imaginary relationship is more important than making a real woman feel loved- he’s a bone head and not worthy of your time. If you aren’t ready to break it off—make him see it your way and simply date someone else when he goes to the club. He will cry saying “ I didn’t cheat” - you can explain to him that you had your date dance naked for you but you didn’t do him… yet. It’s not like you can go to a strip club- they aren’t available to us women. So you improvised.
You could approach this in a different way. Tell him you are going to a bachelorette party with male strippers. Then come home drunk with your hair all messed up and cloths wrinkled. Tell him what a great time you had and the male strippers had alot more than he did.
Sounds like you need help with your self esteem. You don’t want to go into a long term relationship feeling this insecure about yourself. Get help for yourself. What he’s doing is looking and not touching! if it turns out he’s touching, you’ll find out and then you need to deal with it. Get help!
Shouldn’t even be a question or thought. So, NO !
Love only goes so far! Get rid of his ass and find a real man who will respect you.
Reverse the scenario. Would you look at him differently if you visited hunky male strip dancers? Or is your relationship based on other things?
Drop him. He won’t change.
Leave the person who isn’t worth you
Kick him to the curb
First Off ,You Sound Windy & Needy !!! If The Man Thinks He Needs a Stripper it Needs to See One dance,Prance & Swing From a Pole. He Is A Kid. A Boy. NOT Marriage Material. If He Sleeps With Any Of Them, He Could Bring You An Infection. STD’s. Or Did You Forget It’s Still The CORONAPPOCOLYPST !!! He Is Not Thinking & He Possibly Hangs With The Wrong People. CUT HIM LOOSE. There Is Other MEN that You Won’t Have To Babysit. Or Run Yourself Crazy With Thinking Why Are They Doing This. In Fact ,Him Telling You Is Positive Proof You Aren’t His Type. Move On ,Rawhide !!!
He’s a pig. Will always be a pig, so the only real choice is whether you’re going to live with it or get the hell out.
