Everyone is making really good points. I just want to clarify that I'm not saying anyone is right or wrong; the perspective I presented is based on a theory with a level of validity that's questionable at best. It's no more or less valid than the pro-monogamy view. I choose the lens in which I see the world through based on what is useful for my intentions, and that's just the lens I chose based on how much it makes sense as potential truth in terms of how I want to live my life. I could be right or I could be wrong, but I just wanted to let people know their moral options just in case they thought exclusive LTRs were the only "right" way to go.

Carpe diem.

Even though I am not christian, or religious in general, I do believe having sex creates a 'spiritual' (not the exact word i want though) bond with that person, and when you are in a LTR with a girl you really love, that bond is especially strong.
Now, this is a special thing, valuable connection you have with her. Would you want your girl to do just the same special thing (sex) with some other guy, thus decreasing the value of the bond you have with her?
Through my study of Zen and Tantra I have also come to the belief that sex can be a very spiritual - and even spiritually enlightening - experience. However, I disagree with the notion that something could decrease the "value" of a sexual bond.
Assuming that we're only talking about sexual experiences in which we create and establish this special bond, I believe this bond we're talking about cannot be quantified or measured. This bond has infinite value in the present time and therefore cannot be decreased by any event in any other time. That's not to say that your connection with your lover has no "value" before and after sex. The anticipation before and the reminiscence/appreciation afterward have different sorts of infinite value all unto themselves.
The problem that arises from experiencing this sort of connection, however, is when man chases the illusion of permanence. Nothing lasts forever but the ego tricks you into desiring a permanent legacy for your good feelings. The reality is that spiritual value from a sexual connection only exists in the very moment it is experienced. That, I believe, is one of the greatest pieces of enlightenment you can realize from sex.
Therefore, performing the same act of sex with another person doesn't devalue the performances experienced previously. Doing such a thing has only the potential to spread more love to the world because there will always be a different qualitative essence every time anyone has sex. So, I have absolutely no problem with the idea of a girl having sex with another guy after I've created a special sexual connection with her.

When we broke up she said not to expect to get back together anytime soon, and that she just can't deal with relationships right now. But she was even saying that we can still make out, just not right away, and she even wanted to come out with my friends the following saturday. (she said this a few days after we broke up)
But, these types of girls also can be the jealous girls; so do they have a tendency to come back when they see you unaffected, already out flirting with new girls, dating and having a fun time?
Probably.
My suggestion would be to say on your facebook status that you have a relationship with her and that "It's Complicated." I've always wanted to do that.

Now here's another question, what if you had previous knowledge that she doesn't do relationships well, feels trapped and has a loss of freedom? She said that the last guy she almost dated, she had to break it off even before they started dating due to this. But with me she said yes because she thought things would be different. How would you handle her then? How do you give her a sense of freedom while still in the relationship? Is it for some girls that simply being in ANY relationship they will feel trapped?
Even though I don't do the whole LTR thing, I feel like answering this question anyway so that more people can realize more options.
I almost exclusively do "friends with benefits" relationships, and I make my intentions clear from the get-go. The type of girl you are describing is a great candidate to have this type of fling with. Ideally I juggle two FWBs at a time, and I expect my FWBs to be sleeping with other guys so that the non-exclusivity is optimally mutual.
Doing this sort of thing lets everyone still have - and exercise - their freedom while still enjoying fun sex. Of course, there are disadvantages to this lifestyle. For example some depth of emotional connection is sacrificed, therefore limiting the potential for the best sexual experience possible. However, being only 19 years old I'm too young to commit!

I want to have a fun and diverse college experience! So the sacrifice I make is just perfect.
