Hi Jack,
Girls on dating apps who don’t have bios or have their Instagram username in place of a bio are girls who are clearly not taking online dating seriously. They are not on the dating app to find a partner. If they were, they would take the time to write a well-thought-out bio.
There are girls who use dating sites for selfish reasons that have nothing to do with finding a partner. Some want to promote their social media accounts. Some just want to kill boredom so they chat with you for a short while until the conversation dies and make no effort to keep it going.
Some just like the ego boost of getting so many guys liking their dating profiles and begging for their attention. These are the attention seekers. They are the ones who don’t reply to your messages or only give you one word sentences when they do reply.
Try not to get so caught up with how attractive these girls appear. This is why you clearly see that there is no bio on their dating profile and yet you still message them. You are setting yourself up for disappointment.
Focus on the girls who have actual bios that clearly show that they took the time and effort to put together.
Not all of them reply to your messages, but you get a lot more of them replying and actually putting out an effort to have conversations with you than you do the girls who have no bio or just an Instagram username in their dating profile.
