I'm sure nobody really uses /adv/.
First time poster here, and I wouldn't really come here unless I didn't need to, but I suppose I could use the help, if anyone's willing to give it.
In 2013, I met the girl. Let's just call her Anon. But Anon basically came into my life out of no where. Our love for the same type of music brought us together, and we just kind of clicked. I had a pretty shitty upbringing, and lost my mum to a car accident in 2007. So I was always kind of miserable in it's own way. But for once in my life, I was happy. Someone made me feel like I had a reason for something. We kinda had a thing, which was on and off for a few months, then someone else came along and just took me off her. So basically anon and I stopped talking in late 2013, and I guess that was it. We weren't a part of each others lives. I got into another relationship in March this year, and Anon just walked into my life in maybe August this year. (She just got out of a relationship). Then we started to get close again, but not close close, if you understand what I'm saying.
So basically, I'm still hopelessly in love with her, like I was years ago. I can't bring myself to tell her, because I'm still in a relationship. I guess in a way I feel guilty, and I can't come to terms with what's happening, it's all so sudden and I feel like I'm fucking choking.
What should I do? Pic related
