Well there is this girl....she is now my ex

So there was this girl that I had been friends with for the last three years. While I always fancied her she always was always in long term relationships with other guys. Finally at the end of last year the timing was right, she had been single for close on 5 months, and we were bonding well. I asked her out and we started dating. In the beginning all was going really well, but as time passed issues started to pop up. the day after Xmas her ex invited her over for lunch but we had plans. She started wondering why it was so hard for her to tell him sorry but she cant make it. She told me that she might still have feelings for this guy. To which i replied well i understand you guys were toghether for a long time...etc. Then a mutal friend of ours moved far away, she started crying about that, and well you guessed it, she said she might also have feelings for this guy. near the start of the year it was all too much, she said she wasn't good for me and decided it was best for me if we broke up (like that makes sense right?) within a week of our break up she had found it within herself to "fit in" another guy into her life...quite literally. She said it was just about the sex, but he wanted more. finally after being with him for a month or so, she decided to come back to me. but only after i took her back did this all come out....I gritted my teeth and accepted it, i really wanted us to work. we started to drift apart again and a month ago broke up again, for the same reason as before, she wasnt good enough for me... Anywhos, last night i had supper with this girl and she was telling me about all her new relationships. while she has only "been" with this same guy, she is also stringing along three other guys at the same time... at the end of the day they are all pretty much idiots so im not too woried about them..... turns out I'm still worried about her.....I still care about her....she is my angel....sad as that may sound....and you know the funny thing is that last night we were connecting just like at the beginning....she is still in my thoughts all the time... i cant get her out of my head.....no matter what I try.... and obviously the stories she tells me hurt, they rip me apart inside. I want to spend all my time with her, but I dont know what it will do to me. I don't want to cut her off but part of me knows that I have to. Its like cutting off part of me that Ill never get back or like looking at her for the first time and never wanting to look at anyone else again.... So ya that's my problem....pls help

I read your post and I felt like I should reply for some reason... I guess my answer might seem a bit weak, as I assume I'm a bit younger than you, but I figured it wouldn't hurt. And I'm not trying to give you any answers, this is just my opinion. Honestly, I've been through something that was (as far as emotions go) similar. I guess in my opinion, you're too good for her. If she can't clearly see how much you care for her and realize she already has all the love she needs, then she doesn't deserve you. Just the fact that you would wait through all of this for her shows just how much you care about her. And even if she can't see that kind of commitment and understand how incredible it is, I can promise you that you'll be able to find a girl who can. It's hard to move on from having such strong feelings towards someone, but it might be for the best. My friend told me one time "if even 30% is bad, then it isn't worth it. You deserve more." I'm sorry if anything I've said upsets you, and I'm sure she's a wonderful woman from the way you talk about her. And even if she's almost perfect in every other way, maybe just considering relationships she isn't the one.
