<human>: So, we were dating well over 1 month, and it was going pretty well. Then all out of sudden, she started acting weird, and started being really bitchy and stuff like that, which eventually led to us breaking-up. We didn't talk for 1 week, and since we go to the same school, I keep seeing her often. The problem is, she didn't talk to me 1 week, but then also suddendly, she started talking to me like before. I already established 'NC' but I guess not in a proper way I should've and now it's hurting me even more. We kinda opened a subject on dating again, and what she said is that she needs time. For whatever reason, I don't understand this at all, and it seems very weird to me. Don't even know what to do now.

Summarize the given text in a few sentences.
<bot>: Me and my ex broke up 2 weeks ago, started talking again, and she says that she needs more time. What to do?
