It may be that you genuinely love her but realise its unrealistic to be together. Your love doesn't blind you to reality. You know in your heart you wouldn't be happy together. Sometimes we do love the wrong person , because you can't be together due to having different goals in life, and incompatible in many ways.
It seems the only thing standing between you both is reality. Your heart hasn't clouded your own judgement.
I guess in a way I have. I just dated someone casually and I knew going in that it would most likely not work, he is way younger. It was weird because usually I like someone a lot or not at all. With him I liked him, but did not have crazy feelings for him. But he disappeared on me when he got a new job and since then it has been bothering me and I have wondered why? I still wanted to hang out and have fun with him, maybe if he initiated a serious relationship I would have, maybe I just assumed he wouldn't want something serious with someone so much older? It is confusing but I feel like a relationship would have been doomed as well. I don't know what to tell you, I am equally confused.
Yeah, I have a crush on a guy who I know is no good for me. I wouldn't call them "feelings", more like this huge desire to be physical with him and a wishful thinking that he will change. I would never be in a relationship with him but can't help but burning inside every time I see him or talk to him.
