Breh make sure u file away any texts she sends and any voicemails, social media posts etc. If it is urs u gone want full custody. A tough feat for a man to pull off in court, but not impossible, and she sound like the type to constantly shoot herself in the foot with ceaseless displays of scumbaggery and debauchery. fukk tryna coparent and u dont want this child exposed to her toxic ass without supervision(which dont have to be u, they have people for that).
And dont be above egging her on either. just do that shyt real slick and leave no trails.
She definitely doesn’t sound like she’s done enough for him to remotely get full custody. Depending on the state he should be looking at least 50/50.
But everything you said was spot on. Talk to this lady in a business like manner but like she ain’t shyt still - she will react and dig herself into hole after hole.
Simple stuff but he’s not there yet. He needs to take the dna test asap (I’m still not convince this dude is telling the truth and just putting for the coli)
