30M just want to share my feelings i guess (please excuse my english its my third language)

All i know is to care and listen, to give advice or to shut up depending on the situation. All i know is to compliment all i know is to love someone. But i don’t know the feeling of being loved become no one ever did . No girl has ever cared enough to ask me how i feel or how was my day or to text “i messed you” the closest i got is when i texted “I missed you” and got a reply”yeah me too”. And every single time i wanted someone or loved someone and i got is “You are a nice guy and deserve love but it wont work between us but you deserve love” And i don’t believe it anymore all i know is that i don’t really exit I’m forgettable. I have soothing wrong with me but i don’t know how to fix it because no one ever tells me what it is… Its always the polite way off ending thing and i hate it because if I’m so great why am i lonely all the time all my life always alone . And as time passed by and people keep asking ”why are you single” i cant even answer anymore … I don’t know the truth and what i think is too depressing so i just answer “don’t ask me and all the ones who rejected me”.

I have loving friends and family and I’m not giving up on trying to find the one for me, But when everyone around me is married and everyone keeps asking me “why are you single” this simple question is starting to hurt too much.
