If he's doing them all, you may have just won the love lottery and are on your way to getting a commitment.
If your new beau is doing the majority of things on this list, he's into you big time.
She's Constantly Flirting With Other Men "It's as important to look at a person's actions as it is to listen to his/her words," Sherman says. There's a good chance that "something" she's hiding is a someone if she scrambles to come up with an excuse why you can't come to her apartment. If she says no, see if she gives you a reason why." If it's substantial, like her younger brother is staying with her for the summer before he goes back to college, great; if she has nothing to say, you might be her side guy.
If she says she's being exclusive to you, but you catch her chatting up other men at every available opportunity, that's a red flag. She Won’t Take Any Pictures With You There could be a number of reasons she doesn't want pictures of the two of you.
Conversely, she might want to keep you under wraps if she's currently in a relationship or wants to keep her options open so she's free to date whomever she wants.
"Don't assume this, but if a number of things point to her being non-committal this could be a piece of that puzzle," Sherman adds. She might not know how to explain your relationship to friends and family—especially if you haven't had a chat about exclusivity.
