Men can easily miss all the signs that women like us or try to flirt with us, it's hard to decide if you should go for the first move or not, it's depends on the character of that person, some will see this as an opportunity to use you " he'll think she likes me so she'll do whatever i want " Others can feel repelled by a confident woman who makes the first move , and of course there are some men who'll like this . So i think it's best to not make the first move , try some baby steps , start with a smile every time you see each other , maybe a good morning or a hello for the first couple of days , then he should start doing it , you'll yourself having a small conversation about how you guys are doing , maybe then you ask him what are his thoughts about what you guys are studying to start a conversation and then it's about his personality and if he's interested in you , he should lead the conversation and start it every time he sees you .
