<human>: Summarize the given text in a few sentences.

My boyfriend, 'Abram', and I have been together for a year and a half. Abram is white, I am korean. Our relationship has been amazing up until a few weeks ago when my boyfriend started to get suspicious of who I have been texting in Korean. I am constantly reassuring him that I am only talking to friends and family but he does not believe me no matter what I say, and it's starting to make me rethink our entire relationship. 

A few months ago, I traveled to Korea to visit family and friends who still live there. I recently came back to America.  My friends, my boyfriend and I went out to dinner to catch up. While I was telling them about my trip my friend asked if I had hung out with 'Junsun'. Junsun is my ex boyfriend who I dated for almost three years before I broke up with him to come to America. I told her that I didn't and we switched subjects but I noticed Abram was quiet the rest of the night. The day after that, Abram called me and asked me who Junsun was. I told him the truth and he started interrogating me. I was completely honest with him about everything but at the end of the phone call he told me he doesn't believe anything I said. The next time I saw him he asked to see my phone. He looked at all the photos I took while I was in Korea, everyone I had called, and everyone I had texted since then. He then got mad because my contacts and text messages are written in Hangul. He made me romanize all the contact names in my phone but then he says I purposely changed Junsun's name to something different even though Junsun's name isn't in my phone because I don't talk to him at all.

He's very angry with me right now and I don't know what to do because I'm telling him the truth and doesn't believe me. I love Abram a lot and I don't want to lose him over something like this. How do I get him to believe me and to stop being so paranoid over nothing?
<bot>: My boyfriend thinks I am communicating with my ex boyfriend in Korean and doesn't believe me when I say we're not. How can I get him realize that I'm telling the truth?
