The Teen Mom 2 star shocked fans with a new Q&A on her blog that revealed her love secrets.
Lowry, 26, says her split from Lopez, the father of her third son, baby Lux, almost one year old, was incredibly painful.
"I believe Lux's dad was my first true love...I know, weird, when I had two kids with two other people," the reality star said in her question and answer post.
Should her other baby daddies be insulted?
Lowry said of Lopez, her third baby dad, whom she'd split from before Lux was born, "This was my first REAL heartbreak, where I loved someone and was IN love with someone. And I felt so abandoned during such a vulnerable time."
The Lopez breakup hit her particularly hard, Lowry confided to her followers.
"Breaking up with Isaac and Lincoln's dads was upsetting because I felt like my kids lost the family aspect that I craved so badly for them. But this was different," she noted.
Lowry also said her relationships with Marroquin and Rivera are now all about co-parenting.
"I talk to them if/when I see them and that's the extent of my relationship with them," she noted.
"I appreciate everything they do for my sons and I'm glad my sons are able to grow up knowing them. There's no reason for a close relationship between them and myself."
But Lowry also had a gay relationship and in an exclusive interview with RadarOnline.com, Lowry's galpal Dominique Potter told all about her cheating scandal.
Substitute teacher Potter explained how Lowry cheated on her—and said the two had trust issues from the beginning!
"Nothing adds up with her," Potter exclusively told Radar about Lowry.
Lowry and Potter's relationship officially came to an end when the Teen Mom 2 star admitted over Twitter earlier this month that she had hooked up with her ex-husband Marroquin.
Potter contended to Radar that Lowry had cheated on her with Javi back in January when they were still in their seven-month relationship.
Lowry and Potter, 22, officially split in May.
The teacher also claimed that Lowry wanted a fourth child they could raise together.
