Not everyone, has a 'motive'. Not everything, is done 'purposefully' as to cause harm. Some people, live in a world of confusing emotions, themselves.

Living in a world of second guessing everyone elses motives, frames of references, et al, leads us, to not being able to control the one thing, that we can, which is our own reactions and emotions.

It could be a case of cat and mouse. Push/pull dynamic.

Breaking up, brings about a certain blow to the psyche. One feels hurt, cast aside and feelings of a certain level of inadequacy occurs(am I that unlovable, am I that horrible of a person, does this person truly despise me, and on and on and on the questions spin a web in the mind). Part of the healing process from break ups, I've learned through the years, is that a level of acceptance needs to be reached in the grief process. Acceptance, that yes, the feelings were at one point mutually genuine. It's just, right here, right now, this wasn't the best possible relationship for me, because if it were, then I wouldn't be feeling so much pain.

I'm sure, it's not that he doesn't have an affection for you, it's just it didn't work out, like either of you hoped it would, initially, when you went down that path. ((and with that type of acceptance, it's about not going back to something that didn't work, it's about moving on, with the wherewithal to know that you are worthy of someone to come along and treat you in a mutually compatible and respectful way. Moving on, is about freeing up your emotional space and pains so that you are open/available(completely emotionally available) to someone new.))
