Does this guy like me as friend or hidden feelings?

Me and a guy friend close friends for ages via work, we have done sexual stuff in the past about 4 years ago, both had partners. Don’t judge please.

Now I am single , he still with his girlfriend, I had rough year, my dog died, step dad got cancer, and now I have minor cancer scare.
But his girlfriend don’t like me as saw msgs years back when we flirted etc. he promised to never see me as friends, or speak as we work togeather.

But he set up a what’s app group under a different name so we can speak still, he takes me for breakfast to meet up, when I fell unwell, he messaged my step dad constantly, was gonna come to the hospital to see me that night, and pretend had work stuff to her.

He wants to really meet my family, but he at times randomly pushes me away and says I don’t like hugs, don’t come near me.

I am very confused and yet his support with my illness and still pursuing this friendship behind her back shocks me.
Please advise on this, is it general friendship from him, or hidden feelings?

He says him and his girlfriend good. we banter a lot too and he also says am I seeing other guys yet and laughs well says hehe

He brought me perfume a few weeks back, likes to please me too, but avoids situations like nights out with me etc. we meet up alone but more at breaks at work or go for lunch breakfast.

He wary girlfriend sees but just stares a lot
