A guy 3 years younger than me has been attracted to me for a while apparently, we have been sort of friends for years but never particularly close. He often comes in the library where I work and so does his mother, she is very friendly towards me. Last year he walked home with me and my son as he lives near my friend's house where I was staying. I said goodbye to him and pushed the pram down the back alley. He followed me. He pushed me up against the wall and tried to kiss me. I screamed no at him but he ignored me, and I only managed to fight him off because he had a broken arm. That evening I told him on Facebook that his behaviour was unacceptable and that if he ever tried to talk to me again I would tell his respectable best friend. I also told my boss what happened. A couple of months down the line he tries to flirt with me again and I do actually talk to his friend about everything. Last week I was hanging out with my friends and my son, when he shows up and gets drawn into the group. As it has been a year without any contact I don't make a big deal about it. When everyone starts to leave, my medication starts playing up and I nearly pass out. He is the only person who is able to stay, so he walks me and my son to the train station, and waits with us for the train. He then starts talking about how much he loves me. I say 'oh thank you I really appreciate the sentiment' (I am not quite myself yet at this point.) He then says that he will prove it - and then promptly pulls his ding-dong out and waves it in my direction. .. what do I do next time I see him? I have told my boss about this.
