Did I play well here or did my opponent just blunder too much?

Hi everyone, I think I have just played one of my best games so far. I am sure I blundered a few times though. I know that I blundered once in the opening, it was probably because I tried something new. I think I am playing the Nimzo-Indian defense here? Please correct me if I am wrong. Could anyone tell me about my blunders here:

Wow lol I just woke up and got to the computer because I realized that I missed 26...Qxe5. Really strange that I was so generous.

The Nimzo-Indian Defense is this one:

Both of you give a pawn for free in the opening, but maybe you got some compensation since he lost a lot of time with his attack on the queenside, and he forgot to simply finish development.

He move his queen side bishop for the first time in move 34, something like that shouldn´t happen.

Thank you socialista. I know that we both blundered in the opening, but where were my mistakes later on?

Yeah... I often fail to calculate if I don't see anything really forced. I think I need to start studying tactics any idea how to?
