So my boyfriend (M 28)comes from a very religious catholic family. I’m Protestant (F 26) and don’t know much in detail about Catholics. My bf is agnostic and has been since he was 16. Since his parents are very strict and religious he went over 10 years without telling them. So when we got together they were really upset about me not being catholic and him not picking someone within the faith. We live together and that’s another thing they are upset about. The most understandable thing is the baby. I was pregnant when we met and I told him when I found out (it was from a previous person). He decided to stay and when we marry adopt our baby. This I understand his parents being concerned about. I would be too as a parent. The baby is now the least of the worries as everyone has accepted our baby. The religion is the issue. They live in Michigan and we’re here on vacation. My bf decided it was time to tell them the truth after Easter since it’s a big deal for Christians even me. I am a believer as well. Well yesterday he sat down his parents and told them. It didn’t go well. His mother cried and his dad went on a lecture and told us what they’re unhappy about. The night before I had learned that apparently Catholics don’t go to Protestant weddings if one of the people getting married isn’t a catholic anymore. And that’s why they didn’t go to his cousins wedding because it wasn’t in a Catholic Church. Them not going wpuld be a big deal for me. And my bf as well he said he’d be hurt. So I asked them when we get married would they be there or not. They said no because it’s against their faith. And how it’s not a valid wedding because it’s not by the church. I told them I would have a pastor because I believe in god and being united under God. They said it’s not a valid wedding. So one they would not attend that’s a blow to me. 2nd it feels like they are dismissing our wedding. My bf is hurting and I’m hurting. I was honest with them told them it’s a big deal for me and that if they don’t go it will change things for me. His mom asked what do you mean. I told her it would change how close I am to you guys. It would be a while before I’m ready to see you guys again. His mom got angry and raised her voice saying it was unfair to say that. Because it’s not about me and it’s about their faith. I told her I get that but it doesn’t change the fact that it would hurt me regardless. I do understand but I feel like they’re justifying hurting us because they’re hurting because her son is agnostic and I’m not catholic. It insults me because it feels like I’m being treated like I’m also agnostic. They remind me of my dad with their my way or the high way. My dad and I don’t have a great relationship because of that. I feel as I will have to set boundaries with them as well. So now I’m upstairs not wanting to go down because I feel awkward. I had to go down to make a bottle for my baby and I told his dad good morning and he didn’t say anything back. That could have just been him not hearing me. Since knowing this information it means a lot of family won’t go due to the religion. His sister and his brother are very catholic too. They are borderline zealoty if I’m being honest. Theres much more I haven’t written down but I don’t feel very comfortable. I feel like I’m walking on eggshells way before the conversation yesterday. I guess what I’m wondering is if I was out of line for being honest with them about how I felt? And if anyone has been in this position and how did it go? And if any of you guys are strict Catholics is this true? I have never heard of that until now

Edit: I forgot to say my bf wants to elope now and be civil. But I always wanted a wedding with the families. To feel special one day at least. I don’t want to elope. I havent told him this yet
