So he wants me back?

Hi Kevin!
On the 20th day of no contact period at 10 pm in the evening, my ex-boyfriend called me on the phone which I did not answer and he followed it with a text telling me " I’m so sorry. I will marry you", which I did not answer. What am I supposed to do? I’m on my 22nd day of no contact period now and I haven’t break it. My boyfriend is in a relationship right now and the last time I know is that he was having the time of his life. It made me confused the way he texted me that night and he has not text anything or call me since then. I need your advice. Thank you.

How much longer are you planning on doing NC?
