Need advice: I (20M) have been talking to this girl (21F) since last August long distance

Background:
I have been talking to this girl long distance since august last year we hit it off on her alt account on snapchat before we decided that i would stay around and was interested in her so i added her on her personal account and had been best friends with her on it, even No.1 if that carries any weight until end of February.

We had bought gifts for each other as we were hoping to meet in January when she was near me for work but unfortunately couldn’t meet up. We were both eager to meet up but i wanted to make sure it wasn’t the rush of feelings we had so wanted to develop them over time which we agreed to. We would talk a lot daily mostly i know things would fluctuate with her work so some days i’d hear more and some less.

What stayed consistent was our playfulness, teasing, morning or late night talking/snapping, we’d call every month or so roughly. We had confessed that we liked each other and cared for each other before her trip and during it there was still plenty of the characteristics i’ve mentioned. After her trip ended late march to late April i noticed our dynamic changed we began snapping less not so much in morning or evening.

We still have our playfulness, joking, teasing, names moments and she comes back even after periods of not hearing from her max 24hours. But our overall volume has reduced, i understand she’s out of a job now, priorities may have changed, social interaction might have changed etc. Now it’s roughly only 1-5 snaps if i’m lucky a day haha but we remain best friends still on snapchat and still follow eachother on insta which she is less active and has a small following.

My questions/feelings are:

1. Does she still like me and have feelings towards me like she did before her trip as the connection still seems to be there and emotionally is?

2. Should i start to accept more now that this is our relationship rhythm she obviously must still want to talk/snap if we are still best friends?

3. Is there anything i should be worried about, i’ve had a bad previous relationship that messed me mentally and may be subconsciously playing a role in this?

4. Should i move when it reaches august to try to see what she feels about our relationship and if she wants to meet up in person still?
