In a pickle or what?

It's come to my attention, that in the past when homeboy has went to his girlfriend's house after not being able to come into mine, he doesn't answer the phone. the last incidence he did answer but lied about where he was i just happened to hear her in the background and immediately left and came over to my house. i asked him why he keeps going over to someone's house that he is toying with, he tells me it's because i am sometimey with him. Now when he doesn't answer his phone after several attempts I am totally pissed off. SHould I just leave him?
