any support group in Manila you can recommend to a couple like us who aren't married yet, has a child, and aren't keen in opening up our personal problems to our parents? :(

You can try seeking advice from Ateneo CEFAM. They give counselling to couples and families who need guidance. I heard they're a great support group. You can check them here: http://www.ateneo.edu/center-family-ministries-foundation
