Hi Volcomjeans,
When we meet people that we click with, we generally know in an instant because everything feels natural and they appreciate you for who you are. If the she needs to think, deliberate and be convinced before she feels something for you, chances are she is not the one you are looking for. The reason why she got with this guy after a month is because she feels something compatible with this person that she didn’t feel for you. It has nothing to do with time, academic qualification, money, appearence etc which is why it seems so unfair. Having been on the recieving end of this myself, I can understand how frustrating this is but the question is, what are you going to do about it?
Personally, I don’t believe that it is selfish for you want to take your leave. How can you be in a relationship with someone when one party gets what they want (friendship) at the cost of what you want (relationship)? No matter how much you love this person, it is not worth having your self esteem kicked in the face everytime you see her and even if she breaks up with this guy, you will just end up as a shoulder to cry on until she meets another guy. Over time, you will eventually end up resenting her. So instead of holding on, let go. This will allow you to remember you time together fondly and move on to meeting someone who feels the same way about you.
