I met a guy at work and can't stop thinking about him but he's 5 years younger than me. He's single and he knows I live alone. We only work together once a week as he works in a different office on other days. When he chats to me it's general stuff but he tells me things that he doesn't tell the others. We sat next to each other at lunch and he kept messing with his work shirt and wriggling in his seat. He leant over close to me to read parts of articles in the newspaper I was reading. When we were alone he stood up and gently pulled at my hair. Then he stooped over to read the article I was reading again and I was aware that he was leaning into me, my head was nearly leaning on his hip but could have been accidental. As he was chatting at my desk he picked up a pile of paperwork and hit me on the head with it. I said that I'd thought of him during an incident with my friend and he said "oh baby" When I asked what he said he said "nothing" and smiled. I asked him if he could help me with some work unrelated to our job, he gave me his email then 2 hours later asked if I'd emailed him yet. when I said no he was asking why not. I told him I'd email when I was home. I sent him a light email but he's not emailed back, it's been 2 days.
Not sure how to pursue this, he lives 1 hour away and the age gap might put him off. Is he just being friendly as I'm the closest to his age? I'd prefer him to make the move but what if the opportunity goes and it's too late? Please can anyone help?
