Annoying!

Stephanie
My boyfriend recently sent his friends baby mom a message saying how he has always liked her, always will, but has come to terms with them never being a thing. He said he did nothing wrong, but I left for a few days and came back after he practically begged me to. He was telling me "I love you, please come back." But he also told me he was messaging like every girl on his Facebook while I was gone. 
Now, one time we broke up and he said the only way he'd be with me was if I let him go through all my social media and give him all my passwords. And I did. So this time I told him the same rules apply, and he REFUSES to let me. But every time my phone goes off whether it's a message or just an 8ball notification.. if he hears the slightest noise come from my phone he's all over it. "Who was that?" "What was that?" Even if he hears it from another room, he comes in just to ask why my phone went off. It's beyond annoying!!😩 I don't know how much more I can take.
