It depends where the brother is from.
The cultural and moral standards vastly differ from country to country/region.
Also as a president of islamic society at the uni your social iq should be higher and stances more flexible.
You should know that group photos are not that bad, especially wearing hijab.
Concerts seem normal now even in KSA, not to mention other lands.
There are not good for islamic and productivity elite, nor they go in them in whatever land. They are for ordinary low achieving folks, that do not know ibadah to calm hearts or studying, marriages or gyms for similar purpose or everything better, like enjoying optional extra work etc.
Standards are different even what is religious music, example, is that OK?

Posting what is normal for a regular muslim woman in Europe, bikinis, boyfriends, propagating alcohol, travells etc. would probably shock you. Some are even imams daughters having latino lovers (older wealthy playboys), working in academia etc.
It is normal after 9.11., wars etc, especially because practicing muslim men are very low achievers, non productive, uneducated, not having good degrees, scholatships, lack of social skills, worse in looks (not going to gym), unempowered etc.
I can say you need to work on yourself, be a lot more productive (at least thrice, set it for your goal, to make it easier for you) in deen and "dunya" and the right will come inshaAllah.
Read at least a book a week with a lot of duas for guidence.
Study next degree after that one.
Pray salad duha, awwabeen, tahajjud, make dhikr in every idle time and salawat ibrahimi (from last sitting on salah), estegfar, shukr.
Open up a business. Give a lot of sadaqa everyvday and night.
Sadly, polygamy is not allowed and wealthy top achievers get like Russian or homeland mistresses, instead of wives and children, or donations to the local, regional or international level.
If you get achieving better, open up someday a startup, finance a marriage, giveca stipend to a poor student, buy them a flat etc. That is nothing for wealthy.
