Thanks everyone for your insights. I'm learning a lot from you although I am still unsure if I am the OW.
Ex said he's getting divorced, told me (almost) everything about his life including two kids (where they go to school, where he works, etc.). I haven't been to his house though because his divorce isn't final yet and his parents are against it.
The first year he was caring, doting, and everything we wanted from a man although he has always been busy. But tries to spend time with (call) me. The following year he started disappearing slowly. He doesn't tell me his whereabouts, rarely calls, doesn't talk much about his life except about what he feels on that day. Told me he has been depressed, lethargic, etc. It could be MLC according to him. But he's only 37, so I'm not sure.
The last few weeks, I only get good morning messages. Nothing more. When I ask him how he feels or when I open topics about his hobbies, he didn't respond. Told me he didn't want to touch his phone except when it's work related.
We didn't see each other for three months, so I paid him a surprise visit. We talked for a FEW minutes. He went home because he said he was sick. The following day I asked if I could see him one last time before I go home. He said he was so sick and apologized. I got suspicious because that's so not him. He's been sick before but still he spent time with me. Long story short, I found out he played golf and went to work instead of being with me. He was sick, but not too sick not to see me.
When I saw him that night, it was like a different person. The guy who would make sure I was OK, who would go out of his way to call and spend time with me, is gone. I was like talking to a stranger.
I broke up with him out of anger for lying to me.
Two weeks after, I asked why did he have to lie. No response.
I don't know what to do as this is my first time to encounter MLC. My dad didn't have this and none of my uncles had it too.
Oh, well.
