Who has it worse? me or the main girl? do we both have it equally as bad?

for about a year, I was very clearly the side girl of a guy I was seeing that I met on tinder early last year. He added me on fake accounts & a second phone number at the beginning, & when I did some investigating & found his real social media & tried following him on it, he accepted & followed me back, but then blocked me 3 days after, which means he had something to hide. He kept lying & making up excuses & saying he blocked me because I had a go at him for treating me badly, but that was months AFTER he blocked me, so it's obvious he blocked me because he's hiding something, a girlfriend most likely. he eventually added me on his main phone number late last year & he kept playing around & adding & unadding me on his real snapchat. he deleted me permanently on snapchat in the middle of this year & never contacted me or tried to add me back again until he bumped into me 3 weeks ago. he told me he had gotten rid of his side phone & that he no longer uses the fake accounts he added me on at the beginning, & he took his phone out to show me that his instagram is deactivated & that he doesn't have one, but just a few days ago, I noticed he made a new instagram & I know he will never follow me on it, & if I tried to follow him on it, he would definitely block me again. I'm getting really sick of him thinking he can use me as a side chick to sleep with when he pleases just because he knows I still have feelings for him, & it's really hurting me to see how he's happily following other girls from his life & isn't embarrassed about them, whereas with me he won't even contact me from anywhere other than through text, where nobody can see any proof of us being in contact. I know I shouldn't be that envious of the girlfriend, because after all, she is getting cheated on behind her back, but at the same time, I just feel jealous/envious seeing how at least he's proud to have her in his life & how he's friends with her friends & vice versa. I've now blocked his number though.
