advice for others to make friends?

Story lads,just a quick one for yous (new account made to hide who i am)

My girlfriend is a first year in TUS out in Caherdavin area, and she’s struggling to find friends. I, naturally, feel terrible because I have my own solidified friend group and im finding it hard to spend time with just them,because she doesn’t have friends of her own so every time we go out or anything she’ll come with. It’s getting frustrating for me personally because she complains about it constantly, and when I try give advice on how I made friends, she essentially throws it back in my face. I probably come across as a wanker here but i’m just at a loss to be honest. Any advice?
