I met you a year ago. Now it's all about conditionals.
The Zero Conditional
This conditional is used when the result will always happen. It's a fact. We're talking in general, not about one particular situation.
Example: If you meet guys on Tinder, you get new emotions you can write about on your blog
The First Conditional
It's used to talk about things which might happen in the future. Of course, we can't know what will happen in the future, but this describes possible things, which could easily come true.
Example: If I send you a message, I won't open my Facebook page for several weeks
The Second Conditional
It has two uses.
First, we can use it to talk about things in the future that are probably not going to be true. Maybe I'm imagining some dream for example.
Example: If I met you on the street, I would ask you about every detail of your life that I missed
Second, we can use it to talk about something in the present which is impossible, because it's not true. Is that clear? Have a look at the example:
If I had your number, I would call you to say how sorry I am for everything that happened (I don't have your number now, so it's impossible for me to call you)
The Third Conditional
It talks about the past. It's used to describe a situation that didn't happen, and to imagine the result of this situation.
Example: If I hadn't done what I had done, you would have dumped me anyway (at least, that's what I tell myself to get through the day. Sometimes the truth is too hard to accept)
