Just need to vent..

My boyfriend and I have been together 8 months. He lives a little over an hour away which isn't too much of a distance but still a lot for me. Months ago my boyfriend looked through my phone and didn't like me talking to one of my guy friends because he saw him as a threat. I agreed to stop talking to him but later missed my friend and started talking again. I told my boyfriend and he was pissed. Because it was through kik, he logged on and pretended to me at first and then told my friend it was him and started saying shit. I hadn't talked to him but was recently curious what was said so I messaged my friend and my bf had just sent him a message the night before! Again pretending to be me. Trying to "get revenge" on him. He violated my trust by going behind my back and this wasn't the first time. Idk if I'll be able to trust him again.. But every time we have a big fight my bc gets all suicidal and idk what to do..
