@Eesha It was for several reasons - she didn't have a huge amount of free time (due to shift work and her DC) and never gave any indication she wanted something serious. I did ask what she was looking for a couple of times, and she never told me.
It was easy being in her company, and we had a few things in common, but weren't really soulmates. However I grew fonder of her over time, and did start to think I would like things to develop. I always enjoyed her company and felt very close to her when we were together.
At the start of last year she had a lot more free time, but it became harder to see each other during the summer, and we went from seeing each other weekly to sometimes not seeing each other for 2/3 weeks towards the end of the year. She was in contact less too, so maybe had been slowing drifting away for a month or two beforehand.
Towards the end, I did show my feelings a bit more - buying her flowers for the first time, and a few little thoughtful gifts. Maybe she just wanted casual and that freaked her out, or it made her realise I wasn't for her.
I think I'll have to move on - although still confused as to why she ended it, as I am wondering if it was something I did or didn't do. I'm assuming she's still attracted to me, after she said we'd probably end up in bed together if we did meet. I just think it's a shame she couldn't be honest about why she didn't want to see me anymore, and also that she doesn't feel like we can meet even as friends even though she's happy to message once in a while.
