Going to a church service solely to please him, would be you being accommodating.

A meet up that happens to be at a church (which to me spells a safe and relaxed environment) to me, doesn't sound accommodating, but as said above, stepping out of your comfort zone.

If you really don't wanna meet up with this man, don't. But I'm sure a part of you does or you wouldn't have been unsure enough to post.

My advice? Go, enjoy yourself and make new friends.

That way, whether it goes well or not, there's no opportunity for "what ifs"...

Who knows, you might even have funnnn!
