So the first year of my master's program is coming to an end; courses are finished, final projects are being handed in, and there's only a bit of TA work left to be done. I've learned a ton in my first year, I really enjoyed all of my classes and loved my teachers, and I got to work on a lot of interesting projects. However, one thing that I've been severely disappointed in has been on the social side of things; despite my best efforts, I've made zero friends during this first year.
I just don't understand it: I attended as many social events at the school as I could throughout the year, especially at the beginning when we were still getting to know each other and when there were several events specifically for this - and then at the colloquiums throughout the year afterwards. At all of these events, I made sure to have engaging conversations with the other students, asking them about their fields of interest, where they're from, their hobbies, etc - and in general, showing an interest in them. And I continued to have conversations with these students in the halls between classes throughout the year. However, none of these interactions amounted to anything, despite showing an interest to be their friend.
As I later discovered, the students in my program (a small group of about 14 students) are all good friends with each other, and they frequently do things in groups; studying, watching movies, going out for lunch, etc. However, none of them have ever invited me to such events, so I ended up spending all of my time outside of class alone. I suppose it's worth mentioning that my program consists almost entirely of female students, and I am the only male - so I thought this might have factored into their reluctance to invite me to these "all-girl" gatherings.
Do any of you have advice on this matter so I don't mess up again next year? Suggestions would be appreciated, and feel free to ask any questions.
