I left my soon to be husband this morning

So after having a few rough days with being very depressed and upset I woke up yesterday morning and decided that’s it I’m getting out of my funk , took my daughter to swim school started the laundry did some normal things , so the afternoon rolls around and my husband has a very bad attitude I asked him what’s wrong. He kept saying nothing. After the 4th time I said fuck it I went upstairs to my daughters room and put her down for a nap. He then followed me , then proceeded to talk about why he’s upset. He’s upset because I think he’s cheating. And I talked to him about it and why I feel this way , I know it’s my hormones, so we hugged it out and moved one . Fast forward to Sunday morning, I got up not really feeling the breakfast, not really feeling the best but I still got up, now for the past 6 months since we moved into our new home we have been fighting. I have caught him goingtgru my phone on several occasions.so Sunday morning I left my phone upstairs to charge I went down to make breakfast. I forgot something upstairs so I quietly went upstairs to find him once again going thru the phone. Now I’m a big one for privacy, I don’t do it to him . So I bugged on him took my ring off and grabbed my daughter and left . Hours went by so I need to come back here to grab more things for savanna. And he kept crying and telling me don’t leave. But I’m sorry I felt a certain way about him cheating and now he just makes my depressed go worse because he wants to go thru my phone. I don’t have many friends I don’t go out , I stay home take care of my family. So yes when I text my one friend I’m venting to make sure I’m not going rant and over thinking things . Em I wrong? Sorry for the long story but it’s 3 am . But I’m just a mom in need of advice oh plus I’m 7 weeks pregnant with our second.
