Hi there Reddit!

I've been seeing my boyfriend for about a year, and we've known each other for about 2.5. We're both level-headed, reasonable people, and we want to move in together--we've been talking about it for six months now. And since our respective leases are about to be up, we're actively searching for a place.

We see each other every day as it is, sleep over every night, etc. etc. Not only will it save on living expenses, it just makes sense! He works some weeknights and weekends, and I hold down a 9-5. We won't be around each other constantly, and we're both on the same page about cleanliness, duties, etc. Moving in with him is not my concern... It's my mom.

She's pretty old school. Having four older siblings has taught me she doesn't take kindly to moving in before getting engaged or married, two things my bf and I aren't ready to do. And, the way I see it, times are changing. It's not so taboo to move in with an SO if you're both committed and communicative, in my opinion anyways.

So... We're looking at apartments for a mid-August move-in, which means I've got a limited amount of time to break it to her that we're moving in together. I've got a list of reasons why it's a sound decision, but it doesn't really mean anything when it comes to changing her idea of "right" and "wrong."

Has anyone dealt with something similar? How did you let your parents know your decision and how did you deal with the backlash? I'm really close to my mom and would obviously like to avoid pissing her off as much as possible. I don't want to lose her, but am also not changing my mind about my choice to move in with him.
<bot>: Moving in with my boyfriend--my mother doesn't think you should live with someone until you're getting married to them. How do I tell her without severing ties?
