I know the title sounds bad, but hear me out.
I have a best friend, and she has a boyfriend. Last weekend I bought a bunch of cute clothes, and this Saturday we’re planning to watch a play, go to the gym, and then go swimming. At first, her boyfriend was in the play, which is honestly the only reason I agreed to go—I don’t know anyone else in it, and I wasn’t really interested.
But now he got kicked out, and he wasn’t even supposed to hang out with us anyway. Somehow the plans changed, and now I’m stuck sitting through a two-hour play with both of them, which I really don’t want to do.
For context, I’m a lesbian. I’m not into men at all, and that’s not going to change. I’ve barely even met her boyfriend in real life—just once at Walmart, and it was literally a quick “hi.” On top of that, I don’t like him. He cheated on her and basically manipulated her into staying, which already makes me uncomfortable.
Anyway, I was planning to wear jeans and a tube top. It’s not revealing—no cleavage, no stomach, just a normal outfit. But my friend told me “do not wear that” because she’s worried her boyfriend will somehow fall in love with me.
I don’t want to wear a sweatshirt on a hot day, and I also don’t want to default to my usual band or horror shirts just to make her feel better. That’s basically my whole wardrobe, and I was actually excited to wear something new that I feel good in.
What makes it even more frustrating is that she asked to borrow one of my tube tops, and I said no. For context, she has a much larger chest than I do, so it wouldn’t even fit the same way anyway.
I’m just really annoyed that she’s trying to control what I wear because she’s insecure about her boyfriend.
So… am I wrong for not wanting to change my outfit just because she thinks her boyfriend might fall for me?
