I was messaging back and forth a couple of months ago with a woman and we seemed to be getting along great. She suggested we meet for a coffee, I responded to say that I would like to and asked when would be a good time. I never heard back from her. I assumed maybe I wasn't assertive enough or something...like I was supposed to suggest a day and time right off the bat instead of asking, or maybe someone better swooped in. Anyway, I was disappointed but just let it go. Now, a couple months later she just 'liked' one of my photos. I'd like to write her since we were getting along really well before, but now I'm not sure what to say - do I acknowledge that we were chatting before, or start as though nothing happened? I assume I shouldn't point out that she cut off the messaging before. It just seems like an awkward message to write since she cut off the communication before. Any suggestions would be much appreciated!
