Questioning our relationship

My real true love was slipping through my fingers. How could this have happened to me? I wanted "us". Why was this intruder known as "the other woman" coming into our lives? More importantly, why couldn't he have expressed what was wrong and come to me, instead of someone else? I would have at least known what was going on in his mind. I would have known what was wrong and tried to fix it, but I didn't even have a clue. This man was such a good man at heart. He helped others, he was courteous and kind, but he often became angry with me. Although he never raised his voice, he soon began saying "ugly" and "horrible" things. Why couldn't he have trusted enough in me, or in our relationship to turn to me and help ME? No, instead, he was "helping" the "other woman" because , well, I just really don't know, but perhaps he felt sorry for her. He should have felt sorry for me, for what he put me through. I so wished that things would have been different, and as hard as I tried, I just couldn't change anything. Don't you sometimes wonder why things happened the way they did?
