Struggling with family as to place of reception?

Did his parents actually say something to him that would give him the impression that it would upset them if the reception was at your parents' home?

Seems odd because it is within your budget and the vibe you guys want. Maybe try talking to him again about it because it seems strange he is against it if his family doesn't even seem to care one way or another.

What a bummer! It sounds like the perfect place for y'all! Ask him to be specific about why he is against having it at your childhood home. Is it that he doesn't want to take advantage of your parents' generosity, or that he doesn't want the wedding to be so far from his parents, or something else entirely? Not to say that his concerns aren't valid, but I don't imagine your parents would offer if it wasn't something they wanted to do. And traditionally, weddings take place in the bride's hometown, so even better if it is at your family home! If his parents want to help more with the wedding, maybe they can help with other costs like the DJ, the florist, his attire, or even your honeymoon. If his parents aren't interested in helping, I don't see any reason NOT to cut costs by having the wedding at your parents' farm. Definitely try to have another conversation with your FH about this, it seems to make a lot of sense for y'all.

Side note, but may be helpful: My FH initially wanted a different venue than I did, but after talking about the reasons I liked the other venue better (Better vibes, Set-up/Take-down help, and Day of Coordinator), he eventually agreed that if it would be less stressful and less work for me, we could go with my choice for the venue, especially since I am doing the vast majority of the planning. In return, he asked that I stopped talking about wedding planning a full week plus several other requests (I already forgot them though because they weren't big requests lol). I think he realized that it was a lot more important to me than it was to him. Hopefully the same happens for you!
