Confused Virgo with indecisive Cancer male

Me (I’m a virgo woman) & my Cancer male have just broken up over the weekend, one of many breakups that have occurred on months on end. I would always be the one getting dumped then the next he would be getting back with me again. We have tried so hard to make things work between one another, we have an amazing bond like no other. Yet the other day I asked him if he loves me, he goes yes he does. I asked him why is he still holding on, then he goes I don’t know, we got into deep conversation and he goes he wants to be single and all this. I feel like I had put so much time and effort into everything with him, only for it to get thrown back into my face again. We haven’t made contact since Sunday yet we still have eachother on Snapchat and have viewed posts… Awkward much?

How do I ever know when the last time will ever be? Because it has happened so many times that I can’t even keep up with the words no more. Is it time that I let go and move on? What would be running through his mind, would he be thinking about me whatsoever? CANCER MALES I NEED YOUR HELP

He's 20 years old but I did things in the past to break his trust and he kind of never let go of it, so trust issues basically. He's taken me back many times as he knew I would change but there would be minor things he wouldn't like. But we get along so perfectly like no other and I know that it hurts me deeply inside, I just want to know what he would even be experiencing in himself?
