Like the title says, I shared a quick lingerie picture with him today. Instead of saying that I looked beautiful of anything, he just responded with a fire emoji. I have anxious attachment and I'm always looking for proof or signs that people don't like me anymore. That's not a good habit, which is why I'm coming to you to ask if it's even worth it to bring up. I don't want to just beleive in my mind that he's losing interest and doesn't like me anymore. I also really don't want to ask him about this if it's just my insecurity speaking. We've been dating for 6 months and I'm just afraid that he doesn't like me anymore now that I'm not a shiny new toy. He used to lavish me with attention and I'm most 100% positive he would have said something like "wow, you're so gorgeous". I haven't let myself go, nothing to my knowledge has changed other than the fact that it's not a super new relationship anymore.

Tl;dnr- my boyfriend responded to a lingerie picture with a fire emoji instead of saying anything. Cause for concern or normal?
