My fiance doesn’t want to get married in a church because of what others think

[Quickrunner91]

My fiance is from a Muslim background, however he isn't Muslim himself. He doesn't mind marrying in a church, however he said that a large amount of his friends from his background wouldn't approve, and they wouldn't turn up to the church as a result. I won't invite many guests from my side (I'd say around 10) so if he doesn't have many too he thinks it will be awkward.
I really wanted to marry in a church.

He’s mentioned before that other peoples opinions matter to him. He’s also said that in the past a girl has manipulated him to not perusing a relationship with another woman(way before he met me). So I’m worried he may be prone to manipulation and trying to please others. This is becoming concerning for me.

Should I try to persuade him or let this go and find an alternate venue?

This doesn't actually make any sense to me. We got married in a church. DH has, through marriage, a large muslim family. They all came to the church, no problem and I honestly have never heard of a muslim person not wanting to attend a church service for a wedding/funeral (just as I have attended services for people of other religious).

If the issue is that he has family/friends who are upset he's not a practising muslim, then that is a different issue that you need to work on as a couple.

If he is not a practising muslim but nonetheless, is also not a practising christian, I can see why he might not want to get married in a church. however, in that situation, he should be honest with you because there are fairly fundamental things and if there isn't honesty up front, you're going to struggle in this relationship long term. In the same way, how important is the church wedding to you? because if it's that important and you can't agree what will happen on this relatively minor point, then how will you navigate the really complex things when you're married? Children being baptised or attending a religious School, for example.

Very good.

Unless you ate religious and regularly go to church then personally I would look at other venues. My fh and I are not religious. We are getting married at registry office. His mum wanted us to have a church wedding like his brother. I personally feel it is hypocrites to go to church just to get married in one. His brother hasn't set foot in the church since their wedding 6 years ago.

I think you both need to compromise to find a venue that suits you both and you will enjoy on the day, that is the crooks of marriage. Churches are religious places and you are marrying someone from a muslim background. So I do think YABU.
