Feel like it's meaningless

Why should I continue to give myself to a man with no intentions for me? I shouldn't have to ask for certain things such as your time or attention? Why should I continue to give you all of me if you're not willing to give all of you? I shouldn't have to ask you if we'll ever go out again or when will I see you again!!! We both work I understand that, but there's a fine line between work life and personal life between us right now! He's losing me and doesn't realize what's about to happen...because right now, I'm not replying even when he's saying, "Good morning Beautiful!" Your actions yesterday showed me everything!!! Why should I continue to be by your side when you won't even be there for me? Why should I continue to love you, when you run hot and cold with me or forever keep me in the dark? You need not worry because that flame has been lit and everything you thought I would never notice, I've been noticing without your consent...see I noticed the way you kissed me yesterday compared to any other day, your hands showed me more, you're either married, we're married or currently separated(that wasn't visible before), you weren't happy and you found me, a way out...your body language speaks volume!!! The things you leave unraveled, I've picked up....I haven't done anything to you, said anything about you, nor stepped out on you, but you, you're about to lose the one thing you claimed that matter most to you!!!! Why should I continue to give my time and energy to man without intentions? Why should I continue to give my body and my soul to man with no intentions?
