Search Results: going slow

I finally met a woman who makes me feel comfortable and had an instant connection with. But from the start, she has said I am not the type of man she wants, although the lines have blurred at times with things she has asked. I didn't want to hear it because I like her so much, but I figured I'd rather have her as a friend than not at all because we get on so well.

Things started slow but grew to where we were talking for hours every day. This is not like me, I don't talk to anyone, but with her it feels natural. even the pauses felt comfortable. I have never got on with anyone like her. I know it's not alpha, but I like the support we give each other.

Our relationship has been purely phone-based for a year because we live apart and neither of us tried to change that until a couple of weeks ago.
The day started great, she text me first, and later she called. It was our best chat yet. 2 hours into the call and I mentioned I was going to be in her town soon, so I suggested we should hang out or get lunch. She reacted badly and we had our first disagreement. She said meeting once would change nothing. The call ended awkwardly. A couple of days later she called me, and I apologised for putting her on the spot, she said I upset her but she upset herself too. I asked if we were OK and she said yes. That call was short but still awkward. We went from talking every day to nothing for 2 weeks which has made me soo down because I felt like I lost my best friend, but yesterday she called me out the blue and was talking like she used to. she sent a couple of texts which had her playfulness back too. The calls were short as I was at work and couldn't talk, but I text her at the end of the day and she didn't respond. I text her again today and she replied with a single word and a smiley emoji
