i had a situationship with someone 2 years ago. we started talking again.

i(17m currently) met a girl online 2 years ago,we talked nonstop,and hung out pretty much every week. we started acting like more than friends sometimes,and she even used the words "i love you" we were 16,so obviously it wasn't that big of a deal, whatever. all of a sudden she stopped replying,and ghosted me,from time to time we traded 3 or 4 texts but she always ended up never replying. i also blocked her one time,out of frustration.

recently she texted me and we started to try to keep contact, we've been talking for 3-4 weeks now again,she told me that she went through some bad times and didn't feel like talking to anyone at all at that time. now she seems to want to connect again,and today we hung out. it felt good,but i don't know what to think about this. im worried She might ignore me again out of the blank,so I don't want to catch feelings. she also studies in another city which makes hanging out harder,but she comes here to visit her parents often.

i need advice on what to do. i don't know if i should even try to put effort into this or not. and overall i feel lost and confused with her intentions in attempting to talk again
