How to meet a boyfriend naturally?

Hello guys,
I would like to ask you for an advice. I have been single for my entire life, I haven’t even had any short – term relationships. I’m 20 year old girl, I study at university. I have a lot of classes, go out often, have a lot of hobbies and interests. I don’t know why finding a soulmate is such a challange for me. I tried almost everything – approaching guys, texting them and talking to them in real life. I look quite pretty so I don’t think that the appearance is a problem in my case. I’m kind, friendly and helpful, I don’t even have any requirements. I meet a lot of people daily because I chose a medical career. I’m not looking for a Prince Charming but a guy that would like to get to know me. Do you have any ideas what I’m doing wrong? I have also tried not looking for anyone and just enjoying my single life – it hasn’t felt alright because I see myself as a wife and mum so…
Thank you in advance 🙂
