The confusing concept of jannah

Islam states there will be no negative emotions in jannah right? For example jealousy but how can you ever take my jealousy and you want me to praise my husband having sex with 72 virgins who aren’t me, don’t look like me and most likely look better than me. You want me to sit by watch my husband cheat on me? I could never ever have peace in a heaven like that and also how do you relax in paradise while knowing your family friends might be burning for eternity?
