I've been with my boyfriend for about eight months. He was married for about eight years and they have a 4-year-old son together. He rarely talks to her; his parents are actually the go-between in matters of the son. I really do not care for the ex-wife; I get the feeling she broke his heart, and I worry that he may still have or re-develop feelings for her. I know he loves me and he is an amazing guy. I truly believe he would never cheat on me. But this is my first love and my mind keeps going to that ugly, jealous place. He really is not doing anything wrong, so why do I feel this way?
