So I (25F) and my boyfriend (36M) have been dating for around fourteen months. I met him through a family friend of mine and we’ve hit it off ever since. However, recently he’s been acting differently. When I was around 12-13 I went to a summer program in the US and met my now best friends (fake names) Jenna and Emma (both 24F). Jenna and Emma are native Koreans and at the time when I met them, weren’t fluent in English and didn’t live in the states and were only there for that specific program. We’ve kept in touch over the years and as I helped teach them English they taught me Korean and we are all fluent in both. Recently my boyfriend told me that he gets upset when he comes home and I’m talking to either Jenna or Emma in a Korean, especially because they speak English fluently. The three of us tend to speak in a mix of Korean and English but mainly Korean because Jenna still lives there with her family. (Emma moved to my country a few years ago but doesn’t live near me). It’s a lot easier for us to speak in Korean because it’s still their native language and I don’t mind the practice, because none of my friends here speak it. My boyfriend tells me that he feels like we’re taking about him and doesn’t like not knowing what we’re talking about. This was a few weeks ago, and I’ve been speaking in English with them ever since but recently a few days ago I slipped up and he walked into our bedroom as it happened and he completely blew up at me. I reminded him that it was a hard habit to break and he told me that he didn’t care and was “tired of us talking about him all the time.” I have never spoken about him at all in Korean with the girls and even if I had it was never negative. He told me he wanted me to stop talking to them completely because “I don’t know how to control myself”. I told him I wasn’t going to give up two almost 10 year friendships because he was upset. He’s been giving me the silent treatment ever since but I can’t help but look at him differently after what he said. I’m not sure if this is a normal couple quarrel or something to be concerned about. Either way I don’t see him in the light I did before and something in my brain when it comes to him has shifted. Am I going insane?
