This is so heartbreaking.

Bethenny Frankel attended her late on-and-off boyfriend Dennis Shields' funeral today in Long Island, and according to sources, the reality star is having trouble coping with his sudden passing.

“Bethenny has been struggling to make sense of Dennis’ death, and no matter how hard she tries she just can’t. For him to die that suddenly with no warning, at least that she’s aware of, it’s just unfathomable. Of course, Bethenny has wondered if she could have done anything to prevent his death, anybody would do the same in her situation, even though, rationally, she knows that she isn’t to blame," a source dished to Hollywood Life.

Cruel Internet trolls are blaming the SkinnyGirl mogul for Shields' death, saying that her recent comments about their relationship on Real Housewives of NYC pushed him over the edge.

"The press reports that the recent episode of Real Housewives might have tipped Dennis over the edge are ludicrous, and extremely hurtful to Bethenny. The show isn’t filmed in real time, so it’s not like her conversation about Dennis not being ‘Mr. Right’ would have come as a great shock to him. He knew exactly where he stood with Bethenny, and what the status of their relationship was, weeks ago," the insider explained.

"When people are grieving they often look for somebody to blame for the death of their loved one, and Bethenny is the obvious scapegoat here, but it’s totally unfair to put that on her. Things may have been complicated between Bethenny and Dennis, but she still loved him, and she utterly heartbroken and traumatized over his death," the source added.

Meanwhile, a new report says Shields death was accidental, that he would never have tried to take his own life and that he was on medication for back pain. Gregory Broccoli, a friend and colleague of Shields' for 20 years, tells Radar: "There's no way that this was intentional. It's impossible. There was too much on his agenda."

Frankel finally broke her silence after the memorial service, by posting this pic of Dennis and her beloved late dog Cookie. "Rest In Peace my sweet babies who gave me endless unconditional love. #nowandforever," she captioned the image.
