Me problems

My lover's advice on a 'friend' I've been uncomfortable with for years seems sound.

The fact is that I'm not okay with her. For a lot of reasons. I have little to nothing in common with her, we have not talked about anything that was not either banal or about her problems in...multiple years, and she really hurt my family.

It's my problem, as I've consistently downplayed how big of a problem this is for our friendship. This was a bad move. It's much better to be upfront with people, even if they will react badly.

Since my wedding is coming up in June, I feel like I have to do this now, as at the moment I'm not entirely comfortable inviting her to my wedding. And my wedding is small enough that no one I don't wholeheartedly love and consistently connect with should be there.

I'm trying to figure out how to bring this up, and what would be most constructive. It's gotten to the point where I almost feel like I'm leading the friend on by allowing her to think we're okay. We're not okay.
