What should I do? Confused af.

Hi guys,

I have been talking to this girl i met in Tinder since April.We had our first date in the first week of May which lasted for 24hrs and have been on three other dates since of which two were sleep overs.Now she thinks we are moving too fast and she wants to slow it down.We are both studying and don't know where we'll end up after six months.We both are confused about what we want out of this since she'll be going to japan next February for six months and we both don't want to do long distance.She also suggested me she wants to take it a bit more casual than serious but during a conversation yesterday she wanted to know what the dating will turn into.Am so confused about what to do now?

We both are really interested into each other but we both don't know what we want and that's throwing us off.

Any suggestions would be of great help.
