This is honestly just how dating apps work.

Getting matches doesn’t really mean much anymore. A lot of people swipe when they’re bored, talk to multiple people at once, or just never reply even if they matched. It’s pretty common to have like 10–20 matches and only a couple actual conversations.

Your texting might be a little formal in places, but I don’t think that’s the main reason girls stop replying. Drop-offs happen constantly even with good messages.

Also something people don’t realize is that the apps themselves affect a lot of this — algorithms, inactive users, people who just collect matches, etc. I went down a rabbit hole about it a while ago and found this breakdown of how Tinder works and its reputation / trust signals:

It actually explains why ghosting and random silence are so common on these apps.

Honestly the best mindset is just volume. Don’t overthink one conversation and don’t get too invested early.
