No, don't lie. It NEVER turns out good. Coming out clean is best solution. It's just a matter of using the best strategies. First tell them how this woman loves you, helps you, inspires you.. to become a better man... Always talk good about her to them. Eg, tell them : How she makes you feel and what she does for you.. Second tell them, show them how much you love her and that you'll do anything for her. Finally tell them as a simple thing she has a kid. Like say for eg.. balfo sostachin eko weten neber.. Then theyll say who's the 3rd person then youll say the name (my gfs daughter/son) This can go two ways.. They'll be weirded out first but accepts her after a while because you love her and all orrr theyll be shocked asf and won't be okay with it. If they do great! awesome! One happy family If they don't demo don't get upset or angry with them. Show them extra love and respect but while also kindly let them know how much they caused you pain for not loving the person you love for something that happened in the past. It only takes time enji they will accept her because you're their son, just don't give up ante. Wish you the best
