I want my ex bf back. What do I do?

Hi, i'm 20F, my ex 20m broke up in the end of september after dating for about 2 years. It was our 2nd one (i know that's bad ahh). In the end of October I asked him out to have a lil convo (obviouly i just wanted to tell about how much I miss him) & he agreed. We didn't make it for even 5 mins into a convo & confessed each others feelings. So we got together again. In 3 days he calls at night. I was in face time w my friend group so i called him back in about 30 mins. He told about wanting to discuss certain moments in our relationship. What he wants from me & what i want from him. So, like, as usuall, more tenderness from me n stuff. The problem i had w all that is just that for some reason he wanted me to make more romantic stuff than he would. And, btw the reason we broke up so many times is that dude just can't talk to me, i mean we can't even have some kind of a discussion. I was the mouthy one. In the beginnig I just though maybe he's shy or he's a listener, so i been sking him about this like why ain't u talking n discussing smth w me. His only answer was that he doesn't know what to talk about. I was okay w that cause Imma be yapping for hours. But my patience drowned after this happening for months. I started to just feel boring for him, like he's not interested in me anymore n he's just sexually attracted. So the first time i just told him straight away i wanna break up, n we did. He didn't even try to stop me, just asked like "r u sure?". But, later i felt very guilty, & as we study at the same uni, i came to talk w him and told that imma very sorry. We became close again n in a month he asked me to be his gf again. I wasn't very sure, as i knew how much pain i brought him the first time w my coldnees. But i still agreed. A year passed. But the reason was not only still the same, one more added: he has i think some kind of problem in a sexual way (like the dihh ain't up bruh). That fact really offended me, cause wym u love me if that thing ain' stands, be so fr, i'm laying nked?!??!?! He promised me to go to the doctor the first 2 times. Spoiler: that never happened. So, these 2 & some other lil things added up & i decided we needa break up. So, this last time we got together in the end of october & broke up, lasted 3 days. The next day i texted him like: hey, i think we did some shit, maybe we'd better sort thing out today? It was unread for about an hour. Honestly, i think ha had seen it, but for some reasons he just didn't want to respond. Btw on that phone call i cried like a dog, for 3 straight hours & this mf didn't even show a slight emotion. At one moment while i was already stressed out he's like: "hey, maybe we should talk about this tomorrow?" LIKE BE SO FR BRO. WYM TOMORROW???!?! Anyways, for the next 2 weeks i called him about 3 times & texted him 1 time when i got drunk. It's been almost a month since we broke up the 3rd time & even though i feel much better, I still love him & hope that we get back again. I just don't know if I should do smth at all???
