My girlfriend never asks me out on her own initiative, and she always replies to my text messages very late.

Personally, I think there are several possible factors:

1. In the answer, she doesn't care about you at all. She has a personality problem!

Your personality is too girly, which makes her uncomfortable.

She doesn't like this communication. Maybe she likes to meet instead of writing short messages.

Maybe she really likes your way, but she likes reading rather than writing.

If I judge the first rule, I will have a good talk with her.

See if she's avoiding it. If this rule is excluded, nothing else is a problem. ...
