Is This Long Distance Relationship Worth It?

Im in this long distance relationship that is going on three years, during the two & half years i've been cheated on. I've forgave her & still in the relationship, I love and care for her with all my heart.... but i just cant get why i am doing all the calling to talk & to see how she is doing...shes not doing it, she quit her job so im paying her stuff plus mines, she never calls, only time she does is when she needs something, how i know cause she always throwing hints at me. what will you do, just stop everything?
