Hi Amy,
When the both of you stopped talking for two days, something may have happened within that time frame that caused him to stop caring for you in the same way that he used to.
Perhaps some other girl came into his life or something may have happened in his life that made him reconsider his relationships, both platonic and those with romantic potential.
It was immediately after this two day break from talking to each other that he stopped flirting with you as much or texting you as much.
At this point in time, he may be just as confused about where to take this relationship or where it is going as you are.
This may be why he still tends to tell you that he likes you. He may not want to shut out the opportunity for romance with you entirely.
However, the longer that the confusion persists, the more comfortable he will become with it. This increases the likelihood that your relationship with him will never get back to where it once was.
