Kailyn Lowry and Chris Lopez may not be dating but they are keeping in close contact for the sake of their young son.

Although Lopez has been keeping a low profile since his relationship with Lowry began last year, even choosing to steer clear of the Teen Mom 2 cameras, he spoke out about his son on Twitter at the end of last week.

Days later, Lopez shared another post.

As Lowry and Lopez attempt to co-parent, rumors continue to swirl in regard to tension between them.

“Kailyn’s relationship with Chris has been like a rollercoaster—full of ups and downs and unexpected turns,” the insider told Hollywood Life days ago. “After he showed up for the delivery, and drove them home from the hospital, Kailyn thought there was going to be a good chance he would actually be in his son’s life.”

Then, after Lopez visited his child numerous times and even brought him a few gifts, things reportedly took a turn for the worse.

“At this point she’s sick of Chris’ bullsh*t, and his flakey behavior,” the insider said. “It’s one thing if he dips in and out of her life, but it’s not OK to do that to a child. Right now she’s one step away from cutting Chris out of her life completely, as she can’t help thinking that having no father is better than having one who constantly upsets, hurts, and bails on his child.”

To see more of Kailyn Lowry, Javi Marroquin, and their co-stars, including Leah Messer, Chelsea Houska, Briana DeJesus, and Jenelle Evans, tune into Teen Mom 2 season eight on Monday nights at 9 p.m. on MTV.
