Monty Brinson, ex-husband of Real Housewives of Beverly Hills star Kim Richards, has been battling cancer for some time – but, as he recently shared on Instagram, his journey is about "to come to an end."
A source close to Brinson tells ET that his family, including Richards, is gathering around him as he's been moved to an assisted living facility, and "nobody knows at this point how much longer he’ll last."
"He seems to mentally be good most of the time, he is just on a lot of medication," ET's source shared.
Richards has been "by his side quite often," the source said, adding that the 51-year-old reality star has "been holding up well" and that she's "at peace with Monty's diagnosis."
Brinson appears to be at peace with his terminal illness as well. He has been open about his battle with cancer in numerous posts shared to Instagram over recent weeks, opening up about his struggle with his friends and followers.
"I'm surrounded by love," Brinson wrote in a caption to a post shared on Monday. "I got plenty of love in my heart. I'm here for everybody. This might be my final resting place but I'm content."
I'm proud of sharing my journey and it's fab out to come to an end.

I'm here for everybody. This might be my final resting place but I'm content explain
In an Instagram post that has since been deleted, Brinson opened up about how difficult it is for him to type, sharing, "I have a friend that will be [here] to help [me] for a few weeks." Much of Brinson's deleted message, originally posted on Monday, was almost indecipherable, and served as a stark look at the challenges his struggle with cancer has presented him.
Back in December, Brinson shared a story about being visited by a minister who wanted to talk to him about life and death.
"I'm not a quitter and no matter what you go through don't be a quitter. No matter your situation," Brinson wrote. "A minster Walked into my room out of nowhere. Asked me if I would like to talk about Life and Death, I said no, cause I'm not scared of death I choose life lll just dig down inside and get all my energy and fight back."
I have had two set backs in the the last months. I'll explain in upcoming post. I'm in the hospital. First of all the fight with lung cancer I'm beating that fight. The set backs concern life or death. Another battle I'm fighting I'm not a quitter and no matter what you go through don't be a quitter. No matter your situation, A minster Walked into my room out of nowhere. Asked me if I would like to talk about Life and Death, I said no, cause I'm not scared of death I choose life lll just dig down inside and get all my energy and fight back at this setback. So I will be celebrating Christmas in the hospital this year. Tomorrow I'm going to get Christmas Tree sent to my room and celebrate life. The I'm going to decorate my room like a fine resort. I'm going to make the best of it. I'll try to get back to phone calls and messages when able. I'll be fine and o would like to thank everyone from all around the world for the prayers and emails I received,, it made my heart stronger and I've felt that much love in my heart.

In an earlier post, in which Brinson shared a stunning photo of a colorful waterfall, he wrote, "My entire life has been like [a] ticket at Disneyland. I've lived thru the highest highs and the lowest lows. Isn't that Life? #thankful #family #blessed #love #life."
"Everyone has had a lot of time to be with Monty during all of this and had their time to process his illness," ET's source shared regarding Brinson's failing health. "Everyone is visiting Monty all the time, his family is always gathering around him."
Richards and Brinson tied the knot in 1985 before welcoming their daughter, Brooke, in 1986. The couple eventually divorced in 1988, but maintained an amicable relationship.
In August, Brinson was one of his wife's most outspoken supporters during Richards' tumultuous summer, which included a stint in rehab, a shoplifting arrest and allegedly being placed on a 5150 hold.
Brinson showed his love and support for Richards on Instagram, sharing a photo of the couple in their younger years and captioning the throwback pic with a supportive message for his embattled ex that read, "I'm excited for her. And personally I would like to thank everyone who stood by her through this rough time."
