Oa lang ba ako or di lang ako maka move on?

Context: ex and i broke up last oct 11 and we had a baby but in heaven. He cheated on me by the way and he’s now with the girl he cheated with. And we never had the “talk” after. Gusto ko sya i approach na sana di nya iopen sa mga girls nya yung about sa baby. And all the personal stories I told him. Oa ba ako or gusto ko lang sya i contact ulit?
