Is this a potentially bad idea?

After a couple bad rebound relationships I was kind of hurt and feeling lonely and I texted my ex (I broke up with her, she said she wanted to remain friends) because I wanted to talk to her about our relationship. We talked for awhile and had a nice conversation and even were comfortable talking about the people we dated after eachother. We texted occasionally since then (like 2 weeks ago), the last time we texted I initiated it and she took forever to text back each time (so annoying lol) and then she drunk texted me at like 4am asking if I was there. Anyway, is it a bad idea to text her? I broke up with her because she didn't "get" me and our differences were becoming to much of an obstacle so I'm not really worried about relapsing, but am I still risking it? And do you think she doesn't want to talk?
