Isn't this disrespectful?

So my boyfriend that I am pregnant by, we've been together for a minute. At the beginning of our relationship he cheated on me with several females and now that he has been around consistently since I find out I'm expecting he claims he hasn't cheated on me but he decided to work with a female who he cheated on and slept with saying it's just business now, I bailed him out 10k and got him out the shelter into an studio and put money in his pockets and he recently just told me he'll fuck my sister and continues to work with this female and doesn't feel like he has said or did anything wrong so I changed the locks at the apartment and took all his stuff. Am I wrong or what?
