So my ex and I have seen each other and talked twice in the past 6 days. We talked for hours and got along so well, the chemistry was there and it felt like how things were before they went south.

We hadn't talked for about 2-3 months since the breakup, and it was a mutual one. I know she loved me, but had a hard time accepting it and became possessive. Right after our breakup we started having sex again like a week after and then decided we needed to completely break things off.

Well now we're gonna try "taking it slow" and I don't really know how to treat it because I know this girl so well. We we're texting a bit but decided there's no need to talk everyday. 

She said she missed me, was lonely, forgave me for the past, and wanted to wait a while before hooking up because it didn't work last time. 

I was thinking I'll just let her contact me and just lay low. I want to do something for her birthday or valentines day but I'm not sure if it's too soon.
