That doesn't work on crazy people

If he had just said "You'll find out in about a week's time," problem avoided.

I don't know why it's such a big deal if your bf/gf looks at your phone. Even facebook and email for that matter. My bf and I have eachothers login info for everything. Sometimes we get eachother to check emails if we're expecting an important message and to clear out junk or *gasp*, sometimes we answer each others phones if we're closer to it :O

I know the password of my boyfriend's email (or anything internet-related as is always the same) and I've never logged in. It's personal and none of my bussiness. And so is his phone, obviously. I think OP is better without someone like her (my boyfriend's ex-girlfriend was like that and ended up tearing all the pictures where he was with another woman, even if that had happened long ago before meeting her)

Exactly 33, i answer my boyfriends phone or send texts for him when he's driving and he uses mine too... i don't see why people are saying "you should never look at your boyfriend/girlfriend's phone" seems very suspicious, like they have something to hide from their partners if they refuse to let them near their phones... of course snooping and just generally using are very different.

My husband and I use each others phones. And yeah, sometimes I read his texts. But that's only because he works with a bunch of idiots and the conversations get quite amusing :) He doesn't care, I never accuse him of anything (if I can trust him on a deployment I'm not going to freak over texts!) and he goes through mine sometimes. I never sneak it away to snoop, it's usually "hey, I'm bored, can I read your texts?" and he throws me his phone! He knows he has amusing conversations in there! If you sneak it away solely to snoop, that's bad, but I think both people being open about it is good!

Hahaha my boyfriend and I always tell the other one to tell there girl/boy friend we say hi! But I do honestly hate the breach of security when I found out he went through my phone/email/Facebook one day looking for things. Yes he found something and over reacted. And should have realized we started dating after those photos where sent. Lol

My boyfriend and I are cool with phone swapping and our computer has auto-log-in so we could access each other's email/Facebook if we wanted to. Sometimes we don't even realize it's the other's account until after we browse a bit since we have a lot of the same friends. I understand being insecure early on (like when he kept getting texts from his ex-fiance), but that stuff should all be in the past if they're considering marriage.

That's been overdone.

He shouldn't have to explain who every female contact in his phone is to his girlfriend. If he wanted to keep something private, she should have respected him and moved on. The same thing goes for girls with a boyfriend who does this.

I'm going to assume she didn't recognize the name Melissa and got freaky paranoid and demanded to know who Melissa was.

Yeah. While I agree she sounds insecure, I don't think you handled it well, OP. Plus, if you'd told her what it was...well...guilt can do amazing things. In one sentence you could have shown her how much you love her, how trustworthy you are, and how much damage her insecurities could have done. Also, from that point on, every time she gets accusatory you can just say, "Remember the time you thought I was cheating and almost didn't get your proposal?".
