Feeling Lost in My Relationship

so my boyfriend and I are still very much together after a small misunderstanding where I thought he was cheating but that was not the case. it might be my over thinking but lately it feels like something is off. it could be the stress of everything currently. my family and I have to move. his family is moving as well. his family has a home they need to clean up before it's liveable. my family is trying to clean up my grandfather's house to move into it as well as dealing with an uncle is being very entitled because of the situation. I feel that as of lately something has happened and I'm not sure what. I went through his phone again and I ended up friending one of his exes when she popped up on my Facebook. I lied about going through his phone and then sent a message to him admitting it but he never really said anything about it. I feel like I'm going to have a breakdown and I just don't know what to do.
