I met this girl about a year ago and I really liked her. I consider her my best friend now, but I still have some feelings for her. She has a boyfriend, and I know that means that she is off limits, but that's not really the problem. I talk to her everyday and we always have fun! Everyday she textes me and we have good conversations. I don't think she likes me but that's fine. I've like her a lot but I relize that being one of her bestfriends is just fine for me, and I'm starting to get over it, but there's just that one part of me that's telling me to not let go. This is leading to me not doing things I should be doing just so I can call her and talk to her. I have to somehow figure out a way to just come to the conclusion that she will never be my girlfriend (unfortantely) and to just live life. Do you guys have any ideas for me to get over it and just be her best friend. Its really making me upset because I really like her but I know that she doesn't like me and she has a boyfriend. Can someone please help me out with ideas to get over this? Thank you!

Stick to your own words :-
I know that means that she is off limits!
If you want to remain friends make this fact very clear to her and best practice what you preach.
