Boyfriend cheating?

Anyone had their boyfriend/husband cheat when they are pregnant? 
My boyfriend said to me "i wish you were more slutty like her" about a girl on this tv show we were watching 
Hello I'm 5 months pregnant, gassy, bloated, constipated! Sorry not sorry if I don't feel like jumping on it every day. Like i don't even know how to respond to that. And to top it off he's gone literally from the moment he wakes up until like 8pm 9pm 
He told me yesterday he was "spending the weekend at his bosses house" he's not friends with his boss, they don't hangout.. I don't even know anymore 
Just had to vent
