Ok lang ba na Facebook friend mo pa ang ex mo?

Case to case basis, I would say. Ano ba ang purpose mo bakit mo sya gusto maging friend sa Facebook? If purely friendship na lang talaga and if okay naman sa spouse mo, you may go ahead. But ideally, no need to add your ex to avoid any issues in the future. Like in our case, ung ex ng husband ko FB friend nya and I don't mind at all, but ako hindi ko friend ung ex ko. Ako na din mismo umiiwas sa kung ano man pwede maging issue between me and my husband just because my ex is still visible on my FB account.
