Met this girl about a year ago. We spent several months texting, calling, hung out a few times, but never officially started dating. It never had a 'friends only' vibe either. She's a single mom with a 2 year old so it always seemed like we were getting to know each other before deciding what we wanted to be. It was going well for a while, she would initiate texts/calls/lunch, use lots of emojis, laugh at my jokes, etc. Then about 3-4 months ago, seemingly for no reason at all and literally overnight, she became more distant. She responded less frequently and less often, she didn't joke around in her texts like she used to, etc. Finally, I asked about it a couple weeks ago. She said that she had a lot going on with her daughter, her uncle died, she started a new job with long hours, and that she didn't think she was ready for a relationship right now and didn't want to lead me on. A day or two later I wrote her a letter saying I really liked her, if she wasn't ready to date right now I'd wait, and told her how great I thought she was. She texted me immediately after reading it and only said 'thanks'. I tried calling her a few days later, but she was busy and said she would call the next day. She did call and we talked for a few minutes but she seemed distant or guarded. She was driving home and had her daughter to get in and fed dinner so I don't know if she was just multitasking and distracted. In the week or two since then I have been texting her most days and she texts back right away, quicker than she ever did before, but the texts are usually just to the point. However, she still isn't as playful as she once was. I'm not sure if that was so long ago (3-4 months) that she needs time to get used to me again or what is going on. Is she sorting things out, not interested, adjusting to me liking her,....I just don't know.
