What are the signs s girl is interested in you romantically?

I’m looking for some advice on a situation with a girl I’ve been talking to. Initially, she would reply to my texts and snaps within minutes, and sometimes she’d send messages with kisses (like xx or xxx) and even love heart my Snapchat messages. However, there are times when she suddenly ghosts me for a while.

I know she’s quite an anxious person, so I’m not sure if this is just her way of dealing with things or if she’s losing interest. Has anyone experienced something similar? How should I approach this without making her feel pressured?

Thanks in advance for your help

When in person, she has given me long hugs before.
