I have made good friends with a work a colleague,I originally thought he was gay but not so sure anymore,here are the signs,please tell me what you think;he always teases me,helps me only,advises me and tries to cheer me up when I'm sad,he said to another work colleague that he thought I had an amazing body when he found out I was trying to lose weight,he looks in his own time the hobbies he knows I'm interested in,he gave me his number and sent me a happy valentines text,I hear him talk about me to others,he always smiles at me and is around me always,then he asked me to go to theatre,something he knows I love doing and asked to go for coffee,then on the day of theatre he treated me so nicely,like a real gentleman,he paid for everything,refused to take money off me,said sooo many times on that day how happy and lucky he felt being with me,he kept complimenting me daying I was the most beautiful and nicest girl at work and that I was his favourite,and that he lives my smile,he kept holding my hand,then he held my hand throughout the walk to the taxi,it felt so weird,I don't know how to act around him anymore,and at work tday I felt like he was really trying to ignore me,but he was still friendly when we did have to speak to each other

It does sound like he's interested in you. Are you interested in him? Maybe you should ask him out for coffee after work, have a talk with him, put it all on the line.
