Op, no offense, but is this a JAMAICAN set up? From you mentioned the whole heap of children for whole heap of women and the marriages which do not seem to display anything apart from ownership and convenience My red flag alert went up. Plus the fact that the two men in your situation appear to want to outdo each other and not contend with what is wrong or right.
If so, then you know that you have to stop thinking about your own convenience and get out of dodge. The "bun for Bun" business never worked and the bringing more children into the carnage is a crying shame, but so it goes.
You have little more time to concentrate on the impending birth. In the meantime, you should leave both of these men. They and you are fooling yourselves if you think that you are setting any kind of example for any of the how much children (whether here or "abroad"). You have a chance here to break what appears to be some loose livity by ALL the adults in the situation. And no, nobody's perfect, but you have waited so long until your child's parentage became a problem for you. I hate to be judgey, but you need to raise your standards. All these well looked after kids with careless parents. Parents providing good clothes and food for their children cannot be used as an excuse for adults to carouse and indulge their instincts and jealousy.
You know what you need to do. You know what you should do. Start acting serious with yourself, man. Cut your losses with both the men. Ascertain who is the latest child's father. Then you need to stop playing games. Nuff children are out there who were "well looked after" who had carousing parents. They have absolutely no template for life apart from "I want it and I must have it". No emotional intelligence whatsoever. Just swag and a charisma that fades with the first good analysis and females who stay with the partner who financially provides the most.
You need to stop with the victimhood and the "who is right not what is right' mentality. You done messed up trying to out slack two men who, just by the scant information that you have provided here are rolling stones who have found a better gravy train here than back home.
I hope you take my advice. It will be hard and long, especially if you are somebody used to instant gratification and reward. Trust me, you switch up your mindset now, the next generation will benefit. This isn't about the "adults" anymore. if you are part of my ancestral community, or are affiliated with it, then you know that we are fighting for our psychic soul. You've had your fun. Time to fix up.
Good luck with the impending birth. Children are a blessing. We shouldn't take advantage of their unconditional love and innocence.
