Should I remain friends

I was recently contacted by a former friend and have mixed/confusing feelings.  For backgtound, we had both expressed our love for each other long time ago.  We would talk and plan out our whole lives while living in completely different states.  We talked and she went through serious hardships with the suicide of a close relative; we still made efforts to be in close contact.  She flew to meet me and I moved in with her, but it only lasted briefly.  Shortly after arriving she said all the feelings she said to me was just drunk talk.  I decided to leave.  It was very hard getting over her, we tried to remain friends after I moved but it made me very tense so I stopped contact.  Now she's contacted me again nearly 2yrs later, still saying we're old friends and that she loves me.  I haven't responded and feel mixed up if I even should.
