chat roulette still works?

My boyfriend has been staying in my tiny apartment for 90% of the last few weeks. Before this all started i found out he had used my tablet to sign onto Chat Roulette. He swears he didn’t actually do anything (yeah right) but even knowing he was thinking about flashing some random girls on the internet really hurt. He’s been deceitful a number of times (DMing other women, obsessively checking his exes instagram, offering to meet an old flame for dinner etc.) and though we’ve been seeing eachother on and off for almost three years, he’s called me his girlfriend for maybe six months or so. Anyway- the only time he’s gone is to do work related stuff or meet up with friends outdoors. Then he inevitably calls me wasted at 5am and we have a big fight. He saves all his curious, passionate, fun-seeking energy for everyone but me. I had planned on leaving him for the millionth time but just never seem to have it in me. Now he’s back from another all-nighter. Lazy as can be. Eating all the food I bought. And snoring on the sofa as usual because he’d rather fall asleep watching tv than next to me. We have sex like twice a month and it’s nothing special. And I’m really pretty! Or atleast I thought so when we first started dating. But I’m lonely most of the time. Wishing he’d just scoop me up and fuck my brains out. All of this sneaking around (me digging through his phone to find evidence to back up my suspicions) has got me feeling insecure and so unwanted. And it doesn’t help that I’ve been following social distancing protocol and spend most days alone knitting, cooking, or cleaning the house. I fantasize about breaking up and running into him months later looking really amazing and totally over it. My god, why is this still a thing?
