Now that Lamar Odom is back on his feet and doing much better, he wants to do whatever he can to thank his estranged wife Khloé Kardashian for all she did while he was recovering in the hospital the past couple of months.

The 36-year-old former NBA player is so grateful for what Kardashian did to help him recover from the near-fatal overdose that left him hospitalized in October that he wanted to make this Valentine's Day extra special.

"If it weren't for Khloe, Lamar wouldn't be alive," a source told Hollywood Life last week. "She's helped him walk, talk, read, and even training him to get back into the best shape of his life. This Valentine's Day, Lamar is planning a very special and romantic evening for Khloe. Yes, there will be flowers, chocolate and her favorite champagne."

When Sunday finally came, the two ended up spending the special day together in a low-key way.

"It was more of friendship than romantic love," a source told E! News. "Lamar appreciates Khloe so much for everything she has done for him these past few months."

The source also explained that Odom got her "beautiful flowers for being the woman and friend he will always love."

Kardashian posted a photo of 42 beautiful red roses to Instagram simply writing "Happy Valentine's Day," and although she did not specify who gifted her these roses, there's a good chance they were from Odom.

She also posted a cryptic quote with a lengthy caption that read, "Spend your time on those who love you unconditionally. Don't waste it on those who only love you when the conditions are right for them."

This comes just days after Odom made his first public appearance at Kanye West's Yeezy Season 3 fashion show at Madison Square Garden during NYFW, as HNGN previously reported. He and Kardashian looked happy as could be as they posed for photos backstage and supported West from the crowd.

 We have to learn to accept the love we AREN'T given. Believe them when they show you their true colors. Stop trying to repaint that person into a shade they are not. To realize, that although we put someone on a pedestal, that does not mean that their judgment defines who we are. We must learn to love ourselves first unconditionally. So we have the strength to not let others love us on their conditions. In conditional love: love is 'earned' on the basis of conscious or unconscious conditions. Conditional love is purely based off of how one can benefit. You, in a sense are paying for another's love. Constantly auditioning for a spot in their lives. Whereas in unconditional love, love is given freely no matter what. With acceptance and purity. Loving is primary. Conditional love requires some kind of finite exchange, whereas unconditional love is seen as infinite and measureless. I think that, at any given point, we are faced with the choice of whether to move on with what the universe gives and takes or to hold on and bury ourselves in our own misery. The choice is yours. Choose your happy over anything else. Love is different for us all. Be strong enough to Accept only unconditional love.
