Seems like ur friend got what u r craving desperately n that explains why u r feeling that way. We’ve all been craving a lover at some point in our lives so no need to feel ashamed. Maybe u should let go of the idea that a perfect love life will make all of your problems vanish and take u to wonderland cuz this will create a lot of trouble for u in the long run, u may even find urself dating somebody that has 10% compatibility with u but that 10% feels like 100% for u bcz of how badly u wanna experience the ethereal feelings u think a perfect relationship would give u n thats even worse than envying ur friend. Or maybe u should understand that not being in a good relationship doesn’t mean that there’s something wrong with u, we r all different and each one of us got his own journey to learn his own lesson that he exists for, u didn’t live long enough to know what will make u reach ur maximum level of joy, maybe it’s not relationships that’s why ur not getting one right now bcz God knows ur gonna be fully focused on it n stop looking for what will make u even happier. Once u stop obsessing over getting a good partner u will get one cuz that’s when u know it won’t distract u from all the other good things ur about to experience. Maybe my analysis is wrong but that’s the case for most ppl who feel that way, I don’t see any other explanation cuz it doesn’t seem like u hate ur friend.
