If a girl is willing to pay for your train ticket to get somewhere, does that mean she is interested in you?

Hi guys was thinking about this recently.

I have been talking to this girl basically everyday since October, and she was willing to pay for my train ticket to go to Church she is Christian and introduced me to the place a couple of months ago, I'm not really religious myself but I'm interested in the morality side of things.

She said "That’s why I say it’s genuinely a pleasure, that’s what I do, I help my friends in need and I feel I’ve experienced the same" and "I can pay for your ticket not a problem at all". She said she is "all ears" when I tell her personal stuff and she spends time giving me advice and occasionally has shared things about her but not a lot.

Part of me is like she wouldn't just pay for anyone's ticket, and she has asked multiple times and said there is no need to pay her back, even though she did mention"friends" in the sentence.

She has called me twice for long conversations and we spoke for 40 mins on the phone, it was very nice

I've realised that I haven't put my intentions that clear, well there is a lot of eye contact and stuff but I think I should ask her out when I see her on Sunday. Like properly.

Part of me thinks that I have accidently friendzoned her without her knowing and now she doesn't want to force anything

Thoughts?
