Breakup (please help)

Okay. So me and my boyfriend were dating for about 2 months it was a really fun good relationship and we didn’t have any problems with cheating, or unloyal, nothing like that. He decided to move in with me sense something had happened. an entire week i was really upset and he didn’t care, I could sit there and cry and he would just walk away.. I tried to talk to him about things and he said everything’s fine. He wasn’t cuddling me, he was always on his phone and I was getting pretty upset with it. (So this one day he leaves early for work (8am)and comes home at 10pm at night, we weren’t talking to each other much that day, he got off at 3 pm that day and I still don’t know what he was doing. So he walks in my room and tells me he’s leaving me. Gets his stuff and leaves. And that’s what happened. I cried and cried 2 days straight because nothing serious happened for us to breakup... so 2 days later he messages me and wants to talk. It’s been 3 days sense this has happened getting everything out with him and trying to fix things and go back to how it use to be. He still hasn’t asked me back out and I don’t wanna waste my time waiting... any advice ?? It was a great relationship until we started fighting and he walked out..
