<human>: A little background information: My ex boyfriend and I have been talking again since September of last year. We broke up in 2012 when we were in a 1 year and 3 month relationship. We have been getting close to each other again recently. It has gotten up to the point where we started saying that we love each other. I should also mention that we live in different states so we communicate through texting a lot.  

   So today we had a situation where we started arguing a bit. It got up to the point where he asked if we wanted to break up. The problem is, we never made it official that we were dating again. We did flirt often and tell each other that we love each other but neither of us made it clear that we were dating. 

When he said that, I got confused because I never knew that he thought we were in a relationship. I told him that I didn't know that and he became very upset. I asked him when he started believing that we were in a relationship and he said that he thought we were when I told him I loved him. 

The thing is, I told started telling him I loved him at least 2 months ago. But just last week we were texting like usual and he said, "I really want you to be my girlfriend but I've been really lonely and sad lately". To me, that made me believe even more that we were not dating. I thought that he was basically saying that he wants me to be his girlfriend but he is unsure yet. 

Was it wrong for me to believe that we were not dating? Does there have to be an official date in a relationship? Any advice you can give as well would help. Thanks.

Can you provide a brief overview of the text?
<bot>: Ex boyfriend believed that we were dating when I didn't believe that we were dating. We never made it official so I didn't believe we were dating. He is upset and I am unsure on what to think.
