Confused - "Could he fall out of love with me so fast?"

I was dating this guy for 8 months. It was kinda long distance but we were able to see each other 2-3 times a week.

We would constantly text each other when we weren't together. He started acting a little different towards me like he was pushing me away but kept telling me he loved me.

He always told me that he knew I was the one for him, that he would never hurt me or screw me over and that he never wanted to lose me.

I went to a party one night and heard that he had cheated on me the week before but I didn't really believe it.

I did ask him about it and he said it wasn't true and he would make sure that everyone knew he loved me and no one else.

We started fighting over stupid things and many times he started them or would keep them going even when I would just try to stop the fighting by saying ok or trying to change the subject.

I went to see him one night and he had a great talk but decided we should break up. It was pretty much his idea and he kept saying he couldnt believe he was letting me walk away from him but he thought it was the best.

Since then, it's been 6 weeks, we have talked a few times, generally me contacting him and each time he says that he's confused and doesn't want a girlfriend right now.

I know he isn't dating anyone else right now but I found out for sure that he cheated on me. I found out yesterday--it was actually a text that my ex sent to someone else that he admitted it.

Could it be possible that he felt so guilty that he just couldn't face me or be with me after he
Cheated? Could he fall out of love with me so fast?

I'm not sure that I want to get back with him but I'm still confused especially after sharing so much together.

It always seemed like he liked me more than I liked him but I am broken hearted especially after seeing the text where he admitted it.

And it wasn't like he was bragging it was just kinda matter of fact. I cheated and she never found out.

Why would he cheat and does that mean he doesn't love me at all anymore?
