It is not about my looks here considering my girlfriend is the hottest girl at uni
But I just can't make friends and have been ignored in groups on several occasions on accounts of being boring
Need some help here. ( will be grateful )
Be confident, and be true to yourself. For the 'boring' part, you can try to get into some activities that you want to do, that you have passion in it or at least, you want to try. And join local events, maybe meetups, concert or such. Either way, try to fill your day with interesting activity that you enjoy.
