I'm pretty open with detailsfor both. He met his ex wife while he was with the Patriots and married her around early 2017 when he was traded to the Giants. At the end of 2017, they welcomed a son but they ended up divorcing shortly after he was born. They co parent now and get along better than they did before.
As for flings, could honestly be anyone from fellow famous people to someone he just finds interesting to someone he met while on the road. He's a pretty social person so it's possible she could be from almost any walk of life.
