<human>: So im not really close to this guy but he invited me over for his birthday party (night) and i was the only girl he invited. The others there were his long time bros. I didnt go in the end though cause i felt it would be weird if i went. Why would he invite me??

There are other times where he did things for me too such as waiting for me after school when he ended early but i ended pretty late. I asked him to wait and he just did for an hour plus. We dont even stay near each other.

There was also this time where i really wanted to eat dinner with him and he rejected at first. On that day, my friend went to tell him that i would be really happy if he went and so he agreed in the end and just showed up. We had a great time, but when we had finished eating, he seemed to be in a rush to get home and kind of moody. I asked him about it the next day and he said he was tired and sick. 

So why would he even come? Also, he didnt seem to have enough money on that day. Before we left, he checked his wallet and asked how much it would be. Eating dinner with us made him spend all his money in his wallet.

The weird thing is i feel that our friendship is kind of weird, at times i feel we are closer and at times we're not. We usually text, rather than talk face to face. And sometimes if we meet, we would go home together.

the weird thing is we dont really talk much. At most in a week we exchange about 50 texts and at times we dont even talk for weeks. So why would he do all that for me when we're not really close?

Can you condense the text into three sentences or less?
<bot>: Does his actions mean anything? His personality is the quiet, cool type of guy but he likes to tease people a lot in his quiet way.
