<human>: My boyfriend and I attend the same University. Yesterday was a really nice day out and I drove to school via car and was late to class, so I forgot to bring a jacket. 

Fast forward to later that day, I was heading home and my boyfriend was staying at school for dance practice. I needed to walk to the car but it had gotten very chilly out. I asked my boyfriend to lend me his jacket and he refused, even though he would be staying at school and I was going to pick him up later. 

I couldn't understand why I couldn't use it since I would be out in the cold and he is indoors. The only reason I could think of was that his outfit wouldn't be complete. I was raised to be very generous with my things and to perform selfless acts, even subconsciously, when you love someone. It is very important that whoever I end up with in the future has that characteristic also.

He couldn't even sacrifice his outfit for my warmth? To me that action directly reflected his character. He is amazing to me but I feel like its important to observe any change in character once the relationship becomes comfortable. We have been together for over 2 years now, and in the beginning stages I know he would've offered without me even having to ask.

I would hate for it to get to the point of marriage, and realize that the gentleman role was only meant to be included during the dating and honeymoon phase. Am I being unreasonable, or were his actions concerning?

Can you give me a shortened version of the text?
<bot>: Boyfriend refused to lend me his jacket to go outside, even though he was staying indoors. I found it unreasonable and inconsiderate; He found me getting upset childish. Who is in the wrong?
