How Can They?

Why do they always end it then start it then end it again? Do they think we don't have feelings? yeah we fall for it because they know all the right things to say. But how can they say all those things and then hurt us so bad? It is always us that gets hurt in the end! They seem to let go so easily but for us it takes so long! their feelings change like the weather, where ours will always be with them! No matter what they do we still think of them! everything reminds us of them! They hurt us so bad but there's still a part of us that would do anything to be in their arms!! They hurt us so bad and act like its no big deal as long as they are ok! They could care less! It makes me wonder did they ever really care or was it just an act?
