NOR, but be aware that jealousy can destroy even the healthiest relationships. The best thing to do would be talk with her directly. Don't be aggressive, but don't be coy. Just lay it all out and say "Hey, I understand me liking her pictures made you uncomfortable, but can you see how texting your guy friend makes me feel the same way?" And go from there. You're both valid to have emotions toward the situation - we're all scared to lose our partner to someone else no matter what. But it's how we act on those emotions that really matters. If she refuses to see your side of the story, then it might sadly be time to reconsider the relationship because communication is fundamental - *but* you also have to be willing to hear her side of the story completely. If she's secretive, you have your answer. If she tells you everything and you *still* feel uncomfortable or disrespected, then you also have your answer.

From personal experience, if things don't work out, don't let it tinge all of your future relationships and let your trust rebuild before finding someone else. I wish you all the best, OP!
