<human>: Hey there! I'm new here but I'd like some advice. So my now ex-girlfriend and I had broken up about 3 weeks ago because of how we were both busy and couldn't really see each other outside of school, but she was very indirect about it. (It ended in me thinking that we were just on a break but after a while, I figured out that by break she meant breaking up.) She still wanted to remain friends and walk with me to classes and chat and stuff.

Well fast forward to two weeks after the break up (when I realized that she broke up with me and it wasn't just a break). I felt kind of overwhelmed and began to over-think things. A mutual friend had told me that she did the same thing to her last boyfriend (asking for space, saying that she wanted to get back together) but never did. This thought caused me to over-think even more and I felt utterly confused. So the following day, I asked my ex for some space, saying that I was going through some things.

I quickly regretted it, I guess because of how foreign it felt and how I didn't fully understand the meaning of space until it was given to me. I tried talking to her 2 days after I asked for space to swallow my pride and ask for my friend back. But when I sat down with her to tell her, we kept being interrupted and I guess that point never got across. I feel so awkward with her now, since I see her everyday. 

I want to be on good terms with her, but I don't know how to get out of "space" and how to mend a friendship. She's a great person and I'd rather have a friend than no one at all. I just don't know what to do... 
Any advice would be very helpful, thank you for your time!
