What IS a healthy relationship?

Well here is another day where I am stressing and feeling anxious. I am struggling with weather or not I have done something wrong to deserve a cold shoulder. He said I will call you later tonight...he didnt call, I was dissapointed and sent a message saying as such. I wasnt mean or rude. Now I get the cold shoulder because he doesnt understand why I sent a message like that. ugh....was I wrong to say something? I would like to think not but I really don't know. Another issue I am facing is the fact he told me if I ever wanted to talk or get out to do something to let him know and he will always make time for me. The issue is, I have to paw at him like a neglected housepet to get him to talk to me, I will wait all day so I am not bothering him, feeling dissapointed that another day went by that he made no effort to contact me first. I am sitting back, playing this through my head, wondering who is in the wrong, him, or I. I cant figure it out. If I had support, a friend, or a family member to talk to maybe I would be able to figure it out, but alas, I am alone. I really don't know how to feel, therefore I seem to be feeling it all at once. ugh FML
