Is FIL feeling bad for MIL’s actions toward me?

So my father-in-law doesn’t leave the house to come visit other people at theirs. Like EVER.

Not even when he’s Grandchildren were born we had to bring them to him.

He’ll attend a wedding, that’s all.

Yesterday he showed up to our place with three HUGE bags of food for us .. I was shocked to hear his voice at the front door.

While putting the groceries away he looked at me and said,

‘We’ll just keep this on the down low, hush hush 🤫’

Keep in mind he also doesn’t go anywhere without his wife unless it’s work, and when I asked where she was he said

‘oh don’t worry about her she went out’

He’s always been so kind to me and from what I’ve heard he’s hated all his sons other spouses.

My opinion is he’s been hearing his wife go on about me and he knows there’s no good reason, so this is how he’s saying sorry in his own way.

( I haven’t been going to their house anymore )

What’s your opinion? Do you think I’m overthinking it all, or do you think he wanted to make us feel good because he knows how bad people are talking about us?
