It could be worse man, I have the same problem, I can't say no to a face that could cry.
She even suggested marriage, after 3 days.
Pretty crazy too, at first I was thinking that nothing will come of it, then all of a sudden I just sorta woke up and suddenly realized that I have to get out of this mess and get out of it right now.
She doesn't really have that much of a unique personality, which is what really bothers me. She just likes whatever I like, does whatever I do, hangs around wherever I hang around, she's like a clone of me that is really driving me insane.
And I was about to get married to her.
Yeah, it's over.
All I can say is, let her down gently, maybe you can still be friends, let her know that.
