Why did Jane Austen never marry?

I wanted to find out why Jane Austen being such a famous romantic writer never married.

In my research I found that her first love (and maybe only love), was a man named Tom Lefroy. He came from a prominent wealthy family who had high expectations of him. He was burdened with supporting his family and sisters. His father wanted him to become a lawyer. Anne Lefroy is the one who might have introduced Tom and Jane.

From what I read online, Jane and Tom had a lot in common, and liked to talk about different authors as both of them read a lot. It seems that Jane may have felt more in love with him than he did for her, as Tom realized his family didn't approve of Jane's social standing and he kept the relationship going a long time before he ended it. I gather that Tom Lefroy's family forced him to marry an heiress, a wealthy woman more suitable to Tom's social standing. After this point when Jane finds out that he has gotten married she never talks about him again. I feel that he must have broken her heart and she never really got over it. I mean this happened when she was about 20 according to my research, and she died when she was 41 years old. That is only 21 years later, that is not a long time to get over someone that she seemed to be very close to over a period of many, many months.

I feel kind of sad for her that she never really found someone to be with. Not that a girl needs a guy to survive in life, but it just makes things easier to have someone to talk to when you are having a bad day or there is some great tragedy happening in your life. I feel like Jane dealt with this by talking with her sister Cassandra. From what I found out it seems that Cassandra and Jane were really close. There was not a single person that could separate the bond that these two sisters shared. They were honest about everything, and left nothing out. Every intimate, secret and detail was shared. I think that is so sweet and amazing, and yet a little sad. Jane confessed that when her sister died she had lost her best friend, a part of herself and that she did not feel that she could communicate or be close to anyone else as she did to her sister. So when her sister died she really was all alone. I just find this idea of Jane Austen not getting married to be a fascinating topic and one shrouded in mystery.
