Guys who are looking for flings are looking for fun, plain and simple, and to them, that means behaving like they’re either a frat boy or still in college.
Yup, that means that this guy is going to down quite a few drinks, and he’ll definitely still be ordering once you’re done for the night. He doesn’t care about the consequences or the fact that it’s a Tuesday evening and you both have work in the morning. He’s going to behave like it’s a Saturday night and he’s partying hard. You can probably tell that this isn’t the type of person that you can see yourself with long-term since he’s basically way too immature to be anyone’s boyfriend (and he doesn’t want to anyone’s boyfriend, anyway).
11 Something More: He Keeps It To One Or Maybe Two
Guys who are boyfriend material, on the other hand, are going to be much more reserved and mature 
. And that means ordering one drink or maybe two if you’re getting along great and want to prolong the evening a bit. That’s a great sign that he likes you as much as you like him, especially if he asks you if you’re getting another one and then orders only when you say yes.
You really can tell a lot about someone from their drinking habits, and if you’re on a first date, you don’t want to drink so much that you get totally messed up and can’t even remember what happened the next morning. That’s how you behave when you party on the weekends in college, not when you’re older and going on dates and trying to find someone who you can be in a relationship with.
10 Fling: He Wants To Leave Early
A guy who only wants something casual isn’t going to sit there and chat with you for hours upon end. He’s going to think that sounds like a horrible idea since it’s not like he wants to get to know you. And, again, he’s only thinking about one thing, so that’s always something that you should keep in mind.
When a guy wants a fling, he’s going to say that he has to leave after just an hour or so. This will probably be after he invites you over to his place and you decline his offer. Since you’ve proven that you’re not going to give him what he wants, he won’t really want to stick around, and he might want to find someone who will. Harsh but true, and you’re so much better off without him.
9 Something More: He Talks To You For Several Hours
On the other hand, a guy who is looking for something more (and who, specifically, wants something more with you), will definitely talk to you for several hours.
He won’t mind sitting at the bar or restaurant for four to five hours and just talking. He’ll want to get to know you the best that he can and he’ll be figuring out if he wants to see you again. The evening will be special and it’ll mean a lot to him since he’ll know that he can see you being a big part of his life and his future. which is totally music to your ears. When this happens, it’s basically magical, especially if you’ve been on some really bad dates lately. It almost feels too good to be true.
8 Fling: He Looks At His Phone A Lot
The guy who just wants something quick and casual won’t pay total and complete attention to you. But don’t be offended. He won’t really pay attention to anyone else except for himself, and this is the way that he behaves on every first date.
