<human>: So i've been dating this girl for about 3 months now. She is my first girlfriend I have ever had and we have a ton in common. For her, this is her first i guess serious relationship in college. 

I have a friend who is in the same situation but its a been a bit longer for them, it also is his first relationship. And we have a third mutual friend who also says the friend 1 is only still with her because its his first relationship. 

I really like this girl on basically every level, and I know she has flaws but I don't care about them, its life everyone has them. 

So my question is, how do I know the difference between being inlove with her and just being blinded by her being my first gf?

Also, I'm the type of guy who falls for people fast, but this time I said I'm not going to do that and haven't started having my usual feelings until after like a month.

Can you condense the text into a few key points?
<bot>: First girlfriend for me, first serious boyfriend for her. How do I tell the difference between the feeling of being in a first relationship and live
