How to move on

I have been with my boyfriend for nearly 2 years now im pregnant with my 3rd baby (which i cant seem to get happy about) i found out the day i was planing on leaving him now i just feel stuck, my boyfriend keeps making comments about how he can tell i dont love him and im not attracted to him anymore and he is 100% right in my mind im ready to leave but my heart wants me to stay i dont want to have sex with him which he hates we barely talk he lives in my house bill free it just pisses me off so i guess im asking how can i finally get the courage to put him out i tell him to leave 24/7 and he doesnt its annoying and i finally just want peace
