It's not likely to get better.
Think it through, Sam. You're dating her and her faith is already an issue. Her mothers faith is, too. So take it to the next step. You decide to get married....in a big church? with a religious ceremony? Then you decide to have children. Will you baptise? Circumcise if it's a boy? Now the child asks you about god. Will your wife then let the child develop its own thought process? How will it's grandmother react?
If you are having problems now, when you're only dating, is there any possibility of a rosy future? This might need to be the flavour of your conversation with her.
If you're looking for a life-partner, it's sad but probably true.
I've got to agree with Strega and Unseen here. At some point you need to be looking towards more than the relationship you have now. Do you only want a relationship for an interim period until you are ready to settle down? Are you already thinking of settling down with this woman? If she can't take any criticism of her religion without getting upset now, is that something you honestly think will change in the future? Also, you have to remember that your girlfriend's mom is going to be family. Do you think you can handle that down the road?
If you want to resolve it, then you have to talk about it. Find out why she gets upset. Try to help her understand that you aren't saying anything bad about her. Maybe if you insinuate how dumb something religious is she thinks you are implying that she's dumb. Figure out what the actual problem is, then you can work to solve it.
And if that doesn't work, if the problem proves to be unsolvable... screw your emotions, use your head, and GTFO.
I think he's spending time on trying to make a relationship work. A good relationship shouldn't be work to start with. It's something you just all into and seems natural because of the lack of friction. Now, speaking to him: later on, when you marry, you'll run into sticking points that require negotiation and compromise, but if it's already that way, move on. You may be missing out on Miss Right while your trying to make Miss Wrong happen.
I feel like this is the only time I will have to get a life partner.
I think this has every mature adult here rolling their eyes. That is teenage Romeo and Juliet thinking. If you are thinking of making her a military wife, I think you'll find those marriages tend to be stressful on both parties.
Another sign it won't work: "her mom would throw a fit if our kids aren't baptised..." The better the relations with the extended family, the better the long term prospects for the marriage.
I had a similar issue with a girlfriend who was a hyper-sensitive woo-head. We would argue about everything from religion to homoeopathy. In the end the constant arguing overshadowed any positive element of our relationship and it was time to call it a day. There was simply no long-term sense in carrying on.
Couples Councelling if your thinking of the long term.
I think that you both really have to be on the same page about what you find important in life.
Its like, if you love dogs and cant imagine living your life without one and then you meet someone who dislikes them. No matter what - that dog issue will end up being the thing that eventually causes the problems. You can deal with the small dramas but for the things that are important, the things that you value and that will make you happy - those are the things you need to agree on. Otherwise no.
I like the idea of councelling because i think couples, if they are thinking of a long future together, need to be challenged with really difficult questions.
Anyone who would give up their dog or cat for a mere romantic relationship is probably a sociopath. Human relationships involve bonds that are easily broken. Your pet will be your friend forever.
Ramen. I've always said that I like animals more than people.
Am I being particularly dense this morning? I totally don't get the Ramen reference, unless it's your pet's name.
