These are the times when a couple show their truest selves which could make or break their relationship.
Huffington Post has come out with a list of things that can seal or break the deal for loved up couples.
In the beginning, you go out of your way to present the best version of yourself to your potential mate. Bad moods are concealed. Weaknesses avoided.
So when you punctuate an overly zesty dinner date with throwing up chile rellenos into a parking-lot tree pit, it might be his first chance to see the real, unvarnished, purely-you you. Assuming he doesn't shield his eyes in embarrassed disgust.
The seconds following your first kiss - When this dalliance flowers into a true-love, toothbrush-sharing situation, that first kiss is going to become the stuff of relationship lore, a creation myth shared with your fascinated/horrified children.
Pay attention. You're going to need every detail.
A car ride together can be many things: a peacock-like display of assets; a show of skill and prowess; a date in itself. Whom does he trust to navigate -- you, him or that GPS lady?
Another thing that could seal or break the deal is the time when he cooks for you and fails. It all depends on your reaction.
Or it could also be the other way round when you cook for him and fail.
Making love is one thing, and sleeping together is another.
Here is your future-every-night. So take careful, scientific note of any notable instances of snoring, sleepwalking, larcenous duvet-hoarding and/or drool puddles of unusual size.
And then think carefully before accepting that next sleepover-party invitation, or in 10 years you might find yourself sleeping on the sofa wearing earplugs. (And if you're sure he's worth it, take this moment to invest in a really comfy sofa.)
Another thing you might want to note is when you meet his best friend from back in the day and you see a whole new side of him.
Attending a wedding for the first time as a couple is taking your relationship to a different level.
If he still seemed charming when your pumps started pinching your feet, it's probably a very good sign.
Another thing is the moment you're tempted to tell a little white lie.
At some point, you're going to have to talk about sex. Nobody wants to. But you gotta.
And how you talk about it might just inform hundreds of intimate moments down the line, so you both had better be as honest as you can possibly muster.
If he's secretly hoping there's a French-maid costume in your shared future, or your interest in 50 Shades of Grey goes beyond writing a book report, and neither of you checks to make sure the other is on board, you're going to end up two not-so-secretly disappointed creatures.
Finding a text from his ex means they still do keep in touch, which will obviously spell doom in the relationship.
