<human>: Give me a shortened version of the text

My ex and I had a wonderful relationship for 5 years.  We were lovers, best friends, held the same interests, and never seemed to get tired of each other.  We lived together for 4.5 of those years and those times were amazing.

The past year got a little rocky.  I started getting angsty about never being able to be "single" during my young years.  The idea of being with him forever wasn't scary, but that part of it was.  I was nervous about the fact that I may be missing something else out there.  I wasn't thinking about this constantly, but when I did, it made me feel impulsive.  I knew he knew how I felt, or something like it, but loved me enough to hopefully see me through it.

We ended up breaking up about a month ago.  The first two weeks were great - I could do whatever I wanted!  But slowly, every day has gotten harder.  Instead of me "going to see what's out there", I find no other man attractive.  He on the other hand, has begun "hanging out with" one of our mutual friends on a pretty regular basis.  We still see each other, as we still have mutual friends and he is currently moving out of our home together right now (which may be one of the most heart breaking facts to deal with right now).  I haven't been sleeping, eating, or really giving a care about much in the world besides when I am going to see him next.

So reddit, I guess my question is, what do I do with myself here?  It is so hard to read him right now - at moments he is super standoffish and seems very happy about the break up - others he is looking at me like I am still the love of his life.  Do I invest time pining after him and trying to get him back?  Like I said, he is currently "hanging out" with someone else.  Do I just swallow my pride and "see what happens"?
<bot>: Broke up with ex because I was scared of being with the same man forever, but now regret that entirely.  Do I try to get him back?
