My girlfriend and I have been dating for roughly 7 months. A couple of days ago, we went out for some ice cream. As we were eating our ice cream we started to scroll TikTok on my phone. When she saw a video she liked, she asked me to send it to her. After I sent it, she asked me to open my inbox on TikTok to check if our streak had been updated yet. When I opened it she saw I had a streak with a girl from my church ‘F 19’. She didn't say anything and we just continued on with our day. The next day she told me that she felt disrespected that I had a streak with another girl, and that she wanted me to stop messaging her and end the streak. To be fair, I only have streaks with my girlfriend and the girl from my church, so I can see how that could make her feel uncomfortable. When I tried talking to my girlfriend about it, she said that it bothers her that the girl from church sends me TikTok's when she knows I have a girlfriend. I explained to her that she has nothing to worry about, since I am absolutely not interested in this girl, and that our relationship doesn't go anywhere beyond a friendship. I also asked her if she didn’t trust me. And if so, what could I do to reassure her. My girlfriend says that she's not worried about that, but that even she has stopped talking and sending reels or memes to some of her guy friends when they were in relationships because she wanted them to feel respected and that she wants the same for us.
This is where I am lost. I obviously don't want my girlfriend to feel disrespected, and at the end of the day it's just a TikTok streak. So I am inclined to just stop sending vids to my friend. However, I don’t understand how a TikTok streak is disrespectful towards my relationship with my girlfriend. Is there something I am not seeing? Any advice is greatly appreciated.
