Let me make it clear first:
I once had a wonderful marriage, but I destroyed it myself. It's no use regretting, as the past is gone. Now, the situation is that Dingding (I don't want to call her the "other woman") and I are not married, and we've been broken up for 2 years. I often visit my son. Last night, I asked Lan (my ex-wife) to have dinner with me. She suggested reconciliation, but came with a bunch of conditions. I was like a walking dead in the company all day today. My mind thought of nothing but this problem. I really don't know what to do?
