Advice?

Me and my bf have been together for nearly a year now

He’s a nice guy and would never hurt anyone or anything purposely.

The other day I asked him “what are you up to next week”

And he replied “finishing personal projects”

But he didn’t say what projects, then he stopped talking to me for 4 days

So I hit him up and asked “what you been up to so far” and he said “stuff”

And he’s never been so cold.

I don’t know what’s up and if I should be worried

Also, he’s always asking me when he could grab my boobs etc.

And I’m scared that if one day he’ll ask me to do something and that I refuse to do it, he’ll probably understand, but be disappointed and leave me.

What are your opinions?💗
