<human>: Can you give me the gist of the text in a nutshell?

* We dated for about 10 months.
* I have been in a couple LTRs before, a 2 year and a 5 year. He has been in no previous relationships.
* I feel strongly that I am/was in love with him. He says he feels strongly about me but was mistaken when he said he loved me, or he felt he did it out of inexperience (he said it about 3 months in, I said it 2 months in).
* I ended the relationship because he stopped acting affectionate, stopped making plans with me, and said he had never loved me.
* Despite this, he didn't want to end the relationship. 

When we were together, it was mainly me doting on him, driving to see him, making plans and doing things to support him. I think he doesn't want to lose this and his desire to keep the relationship afloat may be just due to his own self-interest. (ie, he essentially said to me before when I was ending things "no one will support me like you do, no one else is as good at helping me with my problems")

 
However I've just started questioning my entire viewpoint on love -- how normal is it to be in a relationship without loving the other person? How long would you stay in a relationship where your SO didn't love you? 

People who are currently in or have been in a relationship that lasted for a while without admission of love, what were your motives/thoughts/feelings about that?
<bot>: Is it better to move on when I feel I am in love and my partner does not feel that way? When did you develop feelings of love for your partner, or why do you choose not to say you love your partner?
