Pregnant and I think he’s gonna leave

I’m 11 weeks pregnant. Me and my boyfriend have been together for a year, we live together with his 6 year old daughter. Recently he’s been seemingly trying to spark up an argument, he hates my dog (my best friend) gets mad when I hang out with my mom, and is constantly going through my phone. Three days ago I was texting a good friend and she asked how we were doing and I told her we’ve hit a rough patch recently. We’ve realized that we need different things from eachother in the relationship, which is fine I totally understand, not everyone is the same, I need to give him what he needs and he needs to give me what I need. But he disagrees. He continuously told me that this was “stupid” and that we should want the same things. So I simply text my friend and told her “it was about us needing different things from eachother and he thought that was stupid that we should need the same things but we discussed and we’ve been doing better since” and the conversation was over, I didn’t talk negative about him or anything. Well last night I’m in the bath and he comes in and says “you told (friend) that we were fighting and that you think us needing different things is stupid?” Thinking back to our conversation from THAT DAY I couldn’t think of us even talking about relationships, and knowing that I didn’t say that I said no. Well Mr. know it all here pulls out my phone and pulls up the message FROM THREE DAYS AGO and just walks out. Well when I get in bed I go to apologize because I had honestly just forgotten about the conversation. And to tell him that I didn’t say it was stupid at all, I was simply quoting him. He says “don’t touch me, just letting you know, you’ve lost me” ummmm!?!? So I get up at FOUR IN THE MORNING to pack his stupid lunch for work and he doesn’t say a word to me just grabs his lunch and walks out. So I don’t know what’s going to happen but it always just seems like he’s looking for a way out when he starts things like this. Our baby is due in May and I will honestly just be embarrassed to tell everyone that we’ve split up considering he has my engagement ring, and that he tells everyone about and such. I feel like it’s just all a bunch of crap to make himself look better. Advice? /:
