According to a new report, there's more to Sofia Richie's fear that Scott Disick will cheat.
She's apparently given him an ultimatum.
If he goes running back to Kourtney's bed, he won't get to return to hers.
Life & Style reports that though this couple is still together, but that their split may be inevitable.
"Sofia has made it very clear that if [he] strays, it’s over," the insider reveals.
She is particularly worried that he's banging his ex.
According to the source, "She’d hate to see Kourtney [Kardashian] get one up on her."
"Although," the insider admits. "Saying and doing are two different things."
In other words, telling Scott to never cross that line isn't the same thing as following up on her vow to end things if he slips up.
Apparently, she's genuinely worried that he can't resist his ex.
Honestly, a lot of past and present fans of Scott and Kourtney have also gotten that vie.
"Sofia has her suspicions about Kourt and Scott hooking up," the source shares.
"But," the insider continues. "He swears that nothing is going on between them."
Well, as we all know, if a dude is cheating, he'll totally fess up immediately if you ask him.
In all seriousness, though, they share years of history and three children. It's normal for them to talk.
Apparently, a lot of Sofia's alleged concerns come from a place of insecurity.
"Nothing seems to stop Sofia from feeling like the third wheel to Kourtney," the source reports.
That is understandable.
Scott and Kourtney's shared history (and children) means that they have so much life in common.
They have an easy chemistry, even as exes, and can naturally have smooth conversations.
Scott's much-younger girlfriend would notice and might even feel left out of their conversations.
That sounds pitiful.
You know who is not helping this situation at all?
It wasn't so long ago that Scott openly spoke about trying things again with Kourtney.
According to the self-styled Lord: "We always said we’d try to get back together when we’re 40."
Well, Kourtney is going to be 40 in less than half a year -- in April of 2019.
Sofia might be taking that as a very serious countdown.
Sofia was 19 when she and Scott first hooked up. She's now 20.
Now, she's an adult -- Scott may be creepy, but he's not doing anything illegal.
But at that age, she's very likely still feeling all sorts of emotions more strongly than the guy 75% older than she is feeling.
We should also acknowledge that Sofia has already given Scott one of her best years.
She's a young adult and a super hot model.
We hope that Scott is being sensitive to Sofia's feelings regarding, well, everything, including Kourtney.
We also hope that Scott is not taking Sofia or his relationship with her for granted.
Ultimately, all relationships end, and we don't expect that Scott and Sofia's will be any different.
But it would certainly be better if no one, say, cheats or dismisses the other's feelings. People should be nice to their loved ones.
That said, we cannot confirm that Sofia believes that Scott has been cheating.
Do a lot of people believe it? Sure. Has Sofia openly confirmed that it's a suspicion of hers? Of course not.
So we'll take this report with a grain of salt and keep an eye out.
