Bestfriend meets bf for the first time

I am 19(F) and my boyfriend 21(M) recently came to visit me and insisted on meeting my bestfriend from college 19(F) since my 1st sem and I am right now in 3rd sem . He said " I have come to Delhi to meet you several but we never got a chance to hangout with her and also the area nearby your college".

So I talked to my friend and we decided to go out for food and drinks.

My friend was all nice and everything was perfect and there were positive vibes. We went to hauz khas to eat and CP to just walk and look around.

The real problem comes now : When we were eating in huaz khas we got some food that included drinks for ₹1000 and 2 dishes for ₹300 and ₹600 something.

The bill came around for ₹2400 ( few more things added) . My boyfriend paid it all and i know his situation that he is still new to earning and has a lot of expenses but my friend never mentioned splitting and it would have felt weird to split it out of nowhere. (Idk it felt like this to me , my bf didn't said anything about this).

The bill was just the beginning , all the auto rides ( as hauz khas metro is far from hauz khas village we took auto both side ) and we later got some ice cream all of it either I paid or my boyfriend.

It felt a little weird that she did not offer to even split. My boyfriend is very simple, he doesn't give these things any thought but I have seen money issues my life and it has taught me a thing or two.

Am I overthinking or this was how it's supposed to happen?

EDIT-

Since a lot of you are stuck on two words "insisted" and "invited". I guess I need to learn more english and what I meant is " HE PROPOSED AN IDEA BY ME " when he got to know that I am with her right now and it would be lovely for us to get to know and introduce each other.

Second of all , I don't know how you all live by but if I have a friend circle and my bf has a friend circle, I would like to know and meet his friends and I would want my boyfriend to meet my bestfriend from college and be cordial with her too. Atleast you should have an introduction with your partner's friend.

Third problem is - y'all said I had a problem with her not splitting at all. NO The problem is there was no gesture or any act that she wants to pay for anything. She got off the auto thrice and jut stood there simply. When we were running short for change on ice cream thela she was still standing straight looking somewhere else. I glanced a look towards here and there was nothing ki guys I'll Pay or wait lemme check for change.

Some of you said ki she would have assumed ki it's my treat as I asked to go, okay but isn't it basic decency or act of courtesy to ask or show some signs that you are here you are willing to pay even ₹10.
