I applaud you for such a nice commentary on human relationships. It shows you have sat down, looked at society and searched within yourself and have seen how hard it is to be faithful in a relationship...I agree with you! It really is tough, especially, looking at our society today where everyone seems to think wrong is right and right is wrong.
I applaud you for your conclusion (which doesn't force) that rather states your stand/view of how we should treat our relationships. I applaud you even more, because you did not just mention its high-ups but also the pitfalls behind such a take.
However, I beg to bring to your attention one more solution to the problem of infidelity we face. It is something you might have heard before. It is someone, you may not (based on your discussion) have had a relationship with.
I present to you JESUS CHRIST...one who will enable you to be faithful in your relationships. Through Him, what seemed impossible (being faithful to your partner) will become the easiest thing to do. He will teach you what love is. He will teach you what perseverance and endurance is. Do not give in to the trap of the devil trying to make you believe that YOU-MLACHAKE are so weak that you can not be faithful to your partner. It is the devil making you feel so low in such a good way! He makes you feel (and actually acknowledge it with your own mouth) unable to stand your ground! What a liar he is..and what a fool you will be to accept what he suggests to you..
***Oh, and He has a helper, the HOLY SPIRIT, who will walk with you through those hard times and temptations..when you think you can't take it no more, when you feel like you can't be faithful, when you feel lonely and you just need to spoil some ladies' life in the name of polyamory...HE will walk with you, to remind you, warn you and teach you...!
Accept JESUS today, you will tell me the difference...will be waiting for the feedback!
Ubarikiwe.
