Serious question, do you ever want to be taken seriously in a relationship?
Calling the guy (any guy or woman for that matter) when they haven't kept up their end of a bargain, shown any signs of regret, or even any concern after a disagreement, argument or "the talk" puts you in a very weak position. There is a saying, "he who cares the least wins" and while I never used to agree with this and as stupid as it is, it's true. If you put yourself at someone else's mercy, if you show signs of submission, if you allow someone else to dictate your future how can that ever truly be happiness?
You need to man up here. You go out, you do your thing and you don't leave messages that re-assure him that he is in control. In fact you don't even bother calling at all. If he does call you can admit to being immature and realizing it, you can apologize for flipping out even but you make him make that call.
I will go back to being an ass now.
