1. Text messages to ask how I am and what I'm doing.
2. Text messages to tell me what he's doing. One message he wrote was 'I'm at a market getting presents for the kids and it's freezing.' - that's all he put, I thought that was sweet so I invited him for a coffee to warm him up.
3. Chatting to me for 2 hours etc, let me know he liked my company.
4. Looking after the kids whilst I went to see the doctor and when I got home, the lights and heating were on and he had fed all the kids and was cooking my dinner. I was SO impressed.
5. He rang up this cell phone company I was having problems with and yelled at them on my behalf and 2 days later the company sent me a new phone.
6. He remembered our wedding anniversary even though we were about to be divorced.
7. He expressed worry when I told him I was going to Cyprus, and he asked how I would manage at the airport. This might offend some people but I thought it was caring. He phoned me while I was on a train and asked if he could come over for Christmas of course, I said yes.
That's when the sex happened and then it was basically 'erm, Andy, why did we just do that?'
Probably doesn't help you at all as I am the LBS, but they are the things that impressed me.
