Betrayal and heartbreak 💔

I got married very young, after 7 yrs of marriage and 3 kids my husband cheated on me on one of his trips to mexico...I kicked him out and moved on, only to come back together a yr later. We had baby #4, and for the next 10 yrs all was good.... Until he got a FaceBook. Somehow him and the chick he cheated with reconnected, i found out and kicked him out again. i plastered all her nudes and their private messages on his Facebook page ( noone in my family had him as a friend, i had blocked him, and my kids do not have fb), much to my surprise i was being harrased and trashed talked by his family..... Come to find out they are 1st cousins....she lives in mexico so i know nothing happened physically this last incident....But he hid the truth from me for over 10 yrs and says the only reason he entertained   her this last time was because he knew i was talking to guys... I wasnt, but that is his lame ass excuse. And the reason for cheating the 1st time was because she gave him a BJ and things went from there. Again bullsh*t! But now im double hurt, the cheating and now to know who he slept with makes me sick to my stomach..... I cant stop crying... And the worst part his family is OK WITH ALL THIS. I just needed to vent.... 18 yrs down the drain.... 💔
