Towards the end of the semester (after about two months), we were acting like we were literally dating. I'd stay over at her place, we'd cuddle, kiss outside of sex, etc. My program ended a few weeks before hers (she's still overseas). Before I left, we had a mini talk about "us" where she said she is down to casually date but wants to be able to date other people over the summer. I'm not sure if that's significant, as on one hand women take time to develop feelings, let alone with an ex, and it seems like she slowly started to open up to me (went from only wanting to be platonic to casually dating), but on the other hand she could just see me as something casual until someone she sees as better comes along.
So, should I just wait for her to come back home and let her initiate most of the hanging out, etc. and see what happens over the summer? I'm not entirely sure how I feel. I know I'm open to re-exploring a relationship with her as a lot of time has passed and I've reflected on our shortcomings quite a bit but I'm definitely not crazy for her like I used to be.
Left out a lot of details but hope it doesn't affect how things look. Opinions are appreciated.
