she's lovely, supportive, gives you good sex.
Except she had 7 chads before you, each one was better than you.
First chad cheated on her
Second chad she cheated on him
1) how was first chad "better" than me, if he is a dirty cheater and I am an awesome non-cheater? How is he better? How did she find out he cheated?
2) if she is a "supportive" girlfriend, why did she cheat on 2nd boyfriend? How did he find out she cheated? Who was it with?
The other ones were other things..
Need to know what those are too. Why did it end with the other five?
You don't know if she still secretely likes one of her exs
I apparently know about them, so what happens when I ask her?
You mentioned she is "supportive" but I'm not sure what you mean by this.
Does she "support" me in my quest for truth (tells me if she likes her ex) or "support" my feeling happy by lying to me?
And you know that you will not be the bigger cock ever insde her.
How do I know this?
Has she told me the penis sizes of her seven Chad ex-BFs ?
You won't satisfy her like them did.
If that's true what is her motivation for being with me?
By saying she is "supportive" you imply she has pure motives.
What is her explanation for dating me?
Normally that would be a strange thing to ask, but apparently in this scenario she'd told me about her seven ex boyfriends and their penises so she's probably also told me why those relationships ended and how I'm different from them.
You established she was 'supportive' and a supportive GF who brags about her past conquests would then compliment her new BF about how he is better than the previous ones.
