Small wedding regret

If you have the means- meaning can afford- to extend an invite then i don't see why not.

IMO I don't an extra couple would affect the intimacy of a small wedding. Now, the issue would be if you wanted to invite an extra 15-20 guest and couldn't host them properly...

If you have the means then invite her I have regrets of not inviting a certain person to our small wedding.

I understand how you feel. If you have the means then certainly invite her.

One thing to consider is the possibility of offending others who aren't invited. When you draw the line at "immediate family and wedding party only" I think it's less likely for anyone to get offended for not being invited.... whereas if you invite this one friend, other friends may be more likely to feel left out. I'm in the same boat... we are doing a small wedding with immediate family only so I can definitely relate

If you want her there, invite her!

I say if you can afford it invite her

If you have the means, why not? Just make sure you can afford another 2 plates and alcohol so you're hosting properly. If you don't really have the budget I honestly wouldn't worry about it. It's not worth going into debt over.

I would invite her!

Thanks guys for all the advice! It is not a budget issue since we are specifically staying small so we can properly host, I am more worried about what @sbarr6 brought up in terms of not having a clean line of invites and hurting other people's feelings. We definitely have some time to finalize the list and we aren't doing STDs so I still have time to think on it. I appreciate all of your advice!

Invite her if it's important to have her there.

I'm having an intimate wedding of 25 guests. My venue is all inclusive with an intimate wedding package that had boundaries of 20 guests max. Luckily, the venue was willing to extend our guest count to a max of 25 for an extra fee. If you can afford it, your FH thinks it is fair to give you another guest space, and your venue allows it, I think you should invite her. I would also give her a plus one if she is single.
