Hey guys im searching for some help. My ex wife/child's mother recently turned single and im looking to get in there again. Im not really looking to have a relationship but more less have some fun.

She told me about her break up over the phone and that the guy had moved out and all that (Its only been a few days). She then texted me yesterday after dropping our daughter off but it was more less an innocent text. I think (She just asked me to tell our daughter that she wasnt going at the shops and that she loves her) I kinda think she was trying to initiate a convo.. duno. I just said 'oh ok and that our daughter was looking forward to seeing her at the shops but have a good night and she (our daughter) loves her too. She then texted back 'thanx. Love' and a smiley face. She was all jokey with me she came to pick up our daughter which she never was in the past when she was with the guy. Was wondering if yall can offer some help as to how I should go about getting back in there. Responses would be greatly appreciated.
Ive been out the game for a while now due to SA hence im asking, if was like before the anxiety id already been in her bedroom lol.

Thanks in advance,
