Was I out of line?

Ok I want some opinions here.
The other night my FH and I were talking about the amount of guests that we were going to be able to have. I told him that we could have max 125, sending out more invitations of course. He procedeed to tell me that it was at least 150. I didn't get it, so he told me that his mom is going to want to invite all these uncles and cousins. Now we have been together 6 years and we are paying for this on our own. In my mind I was thinking no way! We live in a small town and I figure that if I haven't met these people before than I probably don't need to or won't see them again. Ok, well I kept that part to myself. Anyway so I said, ok well if that is what your mom wants then please let her know that she is going to have to contribuite to the costs.
Welp...that didn't go over so well.
His family list is out of control and we can't handle it, but he doesn't see it. My family invites are small 2 uncles and 2 aunts (and parents). I can't and won't invite more, and if my father had requested I did I would have told him he would have had to contribute.
So, was I wrong or right?

I do not think that you are out of line - if no one is contributing -and you have a budget, then you have the right to decide who to invite and who not to invite.

Good Luck!! It will all work out!

My motto is if u ain't paying then u NOT inviting!!!!!!
Simple!!!!

You are 100% right. My FH and I had this arguement when we first got engaged. His parents are not contributing to the wedding so I told him that they cannot invite anyone other than the aunts and uncles and cousins that I see at every family get together. At first he was upset because they are his parents and naturally he wanted to defend them but it didn't take much for him to see my point of view.
My dad is paying for 95% and FH and I are paying for the rest and it's not right if you ask me!

Thank you all so much for putting me at ease. He just seemed so upset when I first said something.
