So once week I go to an art class in my local college, since art resources are really expensive and the classes are reasonably priced. There is a lot of people around the same age as me, some a little older. As some one who is anti social and has a resting b•tch face, so people think I am a horrible person, despite that I managed to be acquainted to most people on the course. Now to the dilemma there is a guy who I think is flirting with me. I noticed that the way he act around me Is different to others. He always is trying to talk to me, know about my personal life, offering to buy me food after class and makes dirty jokes. Usually I wouldn’t take this as flirting but he doesn’t even have this energy towards the other girls. I know nothing about guys and I am someone who like to dress down since I hate attention. Although I don’t see this behaviour as harmful, if my suspicions are confirmed then I can no longer be in that class as it will be a fitnah for me. But also this is the only reasonable price class in my whole borough, and I am not trekking to another area for a class that probably will cost more. I don’t want to ask my friends this since I am not that close with them and they would probably not take me seriously. What do I do?
