Bachelor Ben Flajnik and Courtney Robertson still engaged, but he’s not being faithful.I guess the show made Ben a little too comfortable with dating numerous women at one time, because he’s seeing at least three while still engaged to the show’s winner, Courtney Robertson, UsWeekly claims.

“Ben began having issues with what he saw,” a source tells Us. “Instead of talking to Courtney about it, he just started avoiding her. They haven’t split, but he basically stopped talking to her.” Instead of talking out things with Courtney, Ben has reportedly been seen going out with three different women, and two have spent the night with him.

On Feb. 17, Ben was spotted out partying in San Francisco. He left Monaghan’s around 2 am with his friends and four girls — two were for him, two were with his friends, reveals an insider.

“Ben seemed pretty toasted, and this woman in red pants came up to him,” notes an onlooker. “It looked like an altercation at first, then he kissed her on the mouth and hugged her. She wrapped her arms completely around him and embraced him. After the kiss, she walked the other way.”

After leaving the bar, Ben and his friends headed for a late night food run and then he took one girl home (according to a source, he met this girl in Las Vegas on Feb. 14). “Ben and this girl looked like they were having a good time,” says a witness. “They were doing weird dance moves, laughing and joking.” The girl stayed at Ben’s and left his home the next day wearing her going out clothes.

The next day, Ben allegedly had another woman stay over . They were spotted making out in a park before heading back to his pad. “The woman’s hands were all over Ben’s body and his hands were on her ass the entire time,” shares a source.

Can you really have pity for Courtney though? Should Ben be cheating on Courtney because he’s now seen who she really is?

“Courtney did develop feelings for Ben,” says an insider. “She cares for him and wants to make it work. [But] Courtney is really frustrated. She’s trying to figure things out, but he isn’t talking to her.”

Ben has reportedly told friends that “things aren’t good” between him and Courtney — but he hasn’t officially ended the engagement. “They have not had a breakup talk, but it’s been very tense between them,” confesses a source. “She feels very disconnected from him, and he can’t stand confrontation.”
