<human>: Hello everyone.
So the title pretty much says it all. I dated this guy 3 years ago. We went on 3 dates together. I liked him a lot except that he was a little overweight. He treated me so well during the dates. He planned for everything and paid for pretty much almost 100% of everything. I knew he was super into me but I just wasn't feeling it with him.
Anyways, I ran into him the other day and we talked for a bit. He looks great! He told me he lost 50 pounds and all that. I asked him out but he directly told me he's not interested!
I don't get it. How can he go from being really into me to not into me at all.
All I think about is him now. What can I do to give me a chance?

Give me a shortened version of the text
<bot>: Went on 3 dates with this guy but stopped seeing him because I was physically not into him. Met up with him 3 years later and am now into him after his weight loss but he is not interested.
