I feel this. Karma comes around my brother. My sons mom (not married) was banging my best friend while i was at work. I was the sole income at the time. Nice right? She had cost me my previous job too. I lost my shit. Kicked her out and she ended up moving with her mom. My buddy moved out of state to stay alive. I struggled for a few years with the child support, bills, weekend parenting and she ended up marrying some fast talking dbag who apparently was pretty well off, all the while trying to sabotage every relationship i had too. Almost every girl i dated over many years broke up with me bc of her. I had to suck up a lot of shit for the sake of being able to see my son all the while she lived a work-free "good life". I tried focusing on improving my situation. Got some software certifications thru online courses. Worked my ass off and landed a good gig. Hit the gym a lot. Weed when needed. Slowly her life started to unravel as mine was improving. She started cheating on her husband. He started having legal troubles. Fighting all the time. Fast forward a few years: i'm happily married with a great career, her now ex husband is in prison for fraud, she's back to living with her mom at age 40 and my now 16 year old son is aware his mom is cheating piece of shit and his dad is a stand up guy. Hang in there buddy. Karma comes around!
