Blatantly disrespectful

On

So my boyfriend of seven years two children and currently expecting one in December decides to not only look at another female as we are in the car driving together but make little statements on another females appearance including damn and mmmmmm. Now I know men are going to look at other women however not while you’re with your significant other and actually make comments about her.... clearly I’m dealing with the swollen feet I’m already waddling and I was already a little puggy prior to getting pregnant so my stomach is definitely sticking out however I don’t expect to be so disrespected by someone who I’ve been with for so long and have history with.. Am I being dramatic maybe it’s the hormones!
