Is his behavior normal?

okay, the following happened:
a good friend had a birthday. Because I love to bake, I baked her a big pie. this was about 25 centimeters high. I took a lot of effort. I made the dough myself, I made the cream myself, I made the whole pie alone and decorated it myself. And because that's my hobby, I've got some practice in it.
Today, I just wanted to bring in the cake, I stumbled over the foot of the boyfriend and the cake fell on the lawn.

Hardly anyone laughed, for that I am incredibly grateful, but this boyfriend. I do not know what I did to him, that he just had to ruin my efforts to be a good friend and to help with the preparations, if he did not get it on his own. My girlfriend even asked me during his presence and he agreed.

sometimes I wonder if he is jealous of me. I do not know why, but it could be, right? I mean, with my eating habits and my lifestyle I would have to look like the bakers on pizza boxes - corpulent.
maybe i spend too much time with his girlfriend. I dont know. I pretty much hold myself back and see most often when she orders bread.
