I recently divorced my wife of 9 yrs on and off together 20yrs. Been separated 9 months. We have 2 children together. For a while I thought we had 3, but during a breakup back in 2008 before we were married she got pregnant by another man. When she first told me she was pregnant she acted like the child was mines. After 3 years of raising the child as my own I started to see he didn’t look like the other kids. This started big arguments with us. She ended up leaving me and I found out through pics on Facebook who his father really was. I was devastated. It was a guy that she had claimed to only be friends with since they were young and she had never delt with him sexually before the one time they conceived the child. I didn’t believe her but I had no proof. 2 years later we get back together and I continued taking on the responsibility of the child and our 2 other children as the other father was a deadbeat. 2015 til 2024 we tied the knot and I thought we had a pretty happy family we even had another child in 2016. Well since our divorce she’s contacted the child’s father again and apparently he back in the kids life and they are changing his to his original fathers name. Found out she lied about only dealing with him when she had the baby. Turns out she had been dealing with this man sexually since before she and I even met. Also found out that since the divorce they are telling each other that they love each other and saw in her phone they are flirting sending nude pics to each other. I feel like such a fool for taking her back, marrying her and accepting the child as my own. As ppl we really make some dumb decisions based off the ppl we love. Well I’m here no divorced, alone, devastated, hurt, embarrassed and kicking myself in the butt for believing her lies. Can’t believe the woman I love would lie to me about this for over 20yrs and secretly be in love with another man the entire time. Looking for strength to accept and move forward.
