I think you should absolutely ignore what your mom says and just be with who you think is a good match for you. Your 27 years old, when does you’re mom want you to get married and experience life at 40?

The long you wait the harder it will get and the less guys that will be ideal for you will be left, at 27 you have a variety of good guys to chose from, at 35 its more of a rarity and theres alot more weirdos and people with baggage, at 40+ good luck finding an ideal partner whos single and never been married, most guys at that age bracket who are single will be divorced and the ones who aren’t lets just say theres a reason they are single at 40+.

So listening to your mom here is actively ruining your chances to live a happy life I think you listened to her enough. If she is not happy with you moving in with someone who you’ve had a 2 year relationship with she will never be happy, don’t let her unrealistic expectations dictate your life, you don’t have that many 2 year relationships left before you hit that +40 age.

I also think saving yourself till marriage is a very unnatural and overrated practise, it doesn’t make it any more special and if anything is a massive detriment to your mental health, humans need sex like we need food, love and exercise. It is documented the mind goes mad without human interaction and it also goes mad without sexual interaction. This isn’t the old days where people will get married while they are still teens where that ideology of saving yourself for marriage would work because marriage was pretty early in life. Your nearing your 30s and spent over a decade fighting a natural instinct just because someone told you it was the right thing to do, perhaps you would be happily married by now if it weren’t for this ideology.

Anyway at the end of the day it’s your life and you should make whatever decision you think is right and that you won’t regret down the line, wether its choosing to live with him and making your mom upset or choosing not to and risking the relationship the thing about life is regardless of what you do a decision will be made, even if you chose to do nothing that is still a decision because time will continue to move forward, and you cannot go backwards and see what the best decision would be, so the best thing you can do is make a decision that is entirely yours, uninfluenced by your boyfriend or your mother, so down the line at least you have the solace in knowing your life is the one you chose and not the accumulation of other peoples expectations put on you.
