i have 1 kid to raise and also has responsibilities with my parents.. but despite that, i never thought of being apart/ away from my son.. bahala lisod kaau pwo kayahon jud nako para nila. i can't afford not having my son with me jud. what i do is i work harder nalang.. i find fulfillment on it man pd.
but with ur case, u r not bad at all.. u have ur own reason to do so, just keep d contact constant and also spend time to bond with ur kids! u r still their mom despite the distance.. just also make sure nga bsag ur apart from them, ur doing something meaningful in life nga para sa ila para they won't be thinking nga u are only doing things for urself only and wla nalang sila apil because they're with their dad.. i hope though that they will be fully with you someday! God bless..
