<human>: Hello! 

Got engaged about a month ago to my favourite person in the world [30 M]. We are ecstatic and have been together for a long time. We hope to have a smallish [70 people] wedding. Partially due to budget but also personal preference. 

However my Eastern European MIL [50ish F] and FIL [55ish M] have decided they need to invite many of their friends (>10). She has claimed that "they will not be our friends anymore" if they aren't invited. They has offered to pay for them, but I am not sure whether this will eventuate. 

I haven't met most of these people and I am not inviting significant family members from my side to keep numbers down. 

This is a tricky situation (aren't all weddings?!) as my partner and I have worked really hard at me having a working relationship with the MIL (she refused for several years to speak english to me and even now conversation is ... scarce). They don't have a lot of family in our country and I don't want his family to feel left out and lonely on the day. But I also want to enjoy our wedding and not have it turn into some European Circus.

Can you condense the text into three sentences or less?
<bot>: Got engaged (yay!). Now the in-laws want to invite lots of people I dont know to our small wedding. Tricky.
