Could you forgive him?

My boyfriend and I got into an argument this morning over messages he seen between this guy and I when my bf and I were broken up last year for five months. It was an exchange of four words but the guy called me gorgeous and “my love” and that set him off that “I let someone speak to me that way”. WE WERE BROKEN UP. anyways he proceeded to call me a “whore” “hoe” and “bitch” than he said “you’re just a hoe, no wonder your pussy is so loose and your pussy lips are so big”

I was completely shocked. I just can’t believe he talked like that to me.. I’ve blocked him on everything but he is calling me from a blocked number leaving voicemails crying begging me to please talk to him, that he was so angry and wanted to hurt me. I feel this is unforgivable. We have been together for awhile and have a lot invested in our lives. We have a future planned but this just threw me for a loop, I am embarrassed and so upset he spoke to me this way and I have no idea if I should try to forgive him or not. Idk.
