Scott Disick hasn’t had any “fulfilling” relationships since he split from Kourtney Kardashian.

The ‘Keeping Up With The Kardashians’ star admits he was “jumping around trying to find happiness” with other women following the couple’s separation.

He said: “I didn’t see the show because I was living it. But look at it from my perspective. She was on vacation with one man the whole trip.

“That looks like a happier scenario than me jumping around trying to find happiness and these girls are not fulfilling that. I’m just not happy with anybody.”

But Kourtney’s sister Kim interrupts the 34-year-old television personality, telling him: “If you found someone that you were happy with, I think Kourtney would be happy for you. But she sees you out and really drinking and really going through it. She just had concern.”

However, Scott – who shares Mason, seven, Penelope, five, and Reign, two, with Kourtney – fumes back, saying she has never said that to him before admitting he feels “insecure” about being replaced by the family.

Speaking on the E! reality show, he said: “Well, she sure didn’t say that. Not once to me. I don’t live the cleanest-looking life. I’m a guy, I’m a little younger, maybe the way I’m getting over her is a drop different. And it’s hard, I don’t really know what to do. It’s like, if I step out of line one way, I could lose everybody in the matter of a second …

“Sometimes I just feel kind of insecure. Like, if Kourtney met somebody, fell in love, got married and then everyone’s like, ‘Eh, we have a new Scott. We don’t really need to be close with him anymore.’ … It’s a scary thing for me.”
