Mad over a dead guy!

I moved in with my boyfriend three days ago because we had a baby. Me and him got together last year February 14. February 8 an old friend of mine died who are used to talk to when I was like 16 and 12 days before he died me and him hung out once and we left on bad terms because he wanted to do stuff and I didn’t. Anyways I was going through a lot at the time and my boyfriend now happened to be sitting next to me at work and I asked him to go out since then we’ve been together. He knows about my friend who died he also told me he wants to know nothing about him. So I marked my calendar for his anniversary of being dead to remember. This morning when I wasn’t home he texted me saying we were done. He told me that I am grieving over an ex boyfriend and that he’s tired of waiting around basically saying that I’m waiting for my friend who died to come back to life he isn’t waiting around for that. My boyfriend never curses and this time he did like he is furious. I told him I only marked my calendar because I wanted to remember what his one year so I could pray. I got home and he hasn’t come at all. He was at the park with the kids and I went over there and he barely spoke to me and then when I was coming home He went somewhere else. I’m so sad and so heartbroken I don’t know what to do. We literally just moved in together a couple days ago we were doing amazing. I love him so much he means everything to me and I try to show him but why is he so mad over a dead person so much to leave me ?
