Three days afterVanessa Marcilfirst claimed that her only child — 16-year-oldKassius Lijah, from a previous relationship withBrian Austin Green— was cut out of Green and wifeMegan Fox’s life years ago, theLas Vegasalum is now bringing forward even more revelations about their relationship.
“Let’s hear [Green’s] side regarding why Kass hasn’t been welcome in their home for 5 years and let’s also hear about what he offered his son on one of his handful of times he’s seen him?” Marcil wrote back to one fan.

“Kass no longer has a bedroom at their house starting 5 years ago,” she added in a lengthier response to another fan. “He hasn’t ever seen Megan again or met his youngest brother. He’s not allowed to know where they live anymore. Isn’t invited to see them on holidays. Not even Father’s Day. They threw out his entire room and gave away his cat without Kass knowing.”
“He has seen his dad in passing in public places including seeing him in Mexico where his dad was doing a publicity appearance for money at that hotel,” Marcil continued. “His dad had a professional photographer there from the hotel take a pic of them.”
“He has been completely cut out of his families lives,” she finished. “Seeing his dad in public sometimes with a photographer present is not being in their lives. In fact it’s even more confusing for him.”

“Once K invited his dad and stepmom to his baptism as a teenager and waited and they never showed up,” she said. “Heartbreaking. Let’s do better for our kids.”

Still, despite the claims that Marcil has shared, she made it clear that she was willing to put it behind her for the sake of their child.
“We have always only wanted to be friends,” she said. “We absolutely could start that today and would accept their sincere apology and they could stop keeping these siblings apart.”
Reps for Green and Fox did not immediately respond to PEOPLE’s request for comment.

In Marcil’s original post, the actress spoke out on behalf of her son and detailed the circumstances around the exes' “heartbreaking” custody battle.
“12 years ago I was served legal papers and then spent 8 years+ defending myself and my son in custody court in response to his father & his stepmother trying to get full custody (that means I would have seen my son four days a month) and then asking me to pay them child support,” Marcil said. “They lost that case & a civil case asking me for 200,000.”
The actress added, “I never spoke publicly in order to protect my then young son from paparazzi that used to follow him & terrify him. I had also never asked for child support of any kind and had never tried to take time away from Kass' dad seeing him. Ever.”

“In the end they lost all of these court cases. The judge called them all ‘Frivolous’ They always had 50% custody and still did when court ended as I had and have NEVER asked for full custody,” Marcil continued. “Kass has never met his youngest brother and is not allowed to know where his bio father, stepmother and three younger brothers live. Custody cases hurt the children only and the truth shall set us all free.”
“Put the kids first you guys. There shouldn’t be a ‘more important parent’ kids love both parents equally no matter what either parent’s struggles may be,” she added. “Kass hasbeen truly heartbroken sincebeing cut out of his other families lives with NO explanation,” she concluded. “Let’s do better for our kids. Let’s share our stories.”
