"太愛佢" actually is simply a "Relative sense" feeling in your heart, you feel that you love him more than he do, you do more than he do, you care him more than he do. This is only a normal psychological reaction. If he suddenly treat you very good, do everything you want to satisfy you, you may not have such a feeling of "太愛佢"....Human being is like that,....
But as in your case, as a man's commment, I really believe that your man do have some serious problem in your relationship already. You better tell him honestly, in a straight forward manner, your feeling, on his act (be specific)....if you really want to save this relationship....
Child is a concern, but shouldnt it be even more worse to let a child grow up in a unhappy environment than to grow up in happy even though single parent family ????
