You have to invite people to specific things, not just a vague idea.

I just finished hanging out with a friend-couple. We did yardwork and drank tea. lol

Create a plan and then invite people to it:
“I’m going to this concert next month, come along?”
“I’m going for dinner later, join?”
“I’m bringing down the patriarchy from within and i would love for you to be there.”
“I’m doing x because y. You should come with.”
